Scent loc Clothing

Recommended Posts

This thread is great! Both of you guys think like I do. I'm convinced that the majority of deer in farm country tolerate ground scent pretty well, they cross it all the time. If you can keep the wind in your favor & control your scent as much as possible, you're in great shape. I've been thinking I had to eventually get one of those suits, but that thought's been taken care of. Boy sure hope the outdoors stores don't go out of business... Some of their other stuff I really do need.

I was beginning to think I was the only one out there that doesn't wear scent-loc camo. I do use scent free soap, scent killer spray, etc, but am really not sure yet if the scent-loc clothing is for real, or if it's more marketing hype... Would like to hear what most of you guys think about this.

Backlash, I have one and use it but last year right after I bought it someone here posted a great piece exlpaining why it may not work. It regarded the ability to "recharge" the suit (get the carbon back so it can absorb odors), which you do in your clothes drier. According to the piece in order to recharge the carbon the suit would have to be heated to a temp that would incinerate the suit. It also explained that if it was that easy to recharge carbon, then why don't the carbon filters on water filtration units just get boiled to recharge? They don't they get thrown away. My point is, I have one, I wear it, but the most important thing is wind direction and being as scent free as possible starting out. If I use scent free soap, use the wind correctly, and then put on my scent loc suit the scent lok won't hurt me. That said, I wouldn't buy one if I were you. Unless you buy mine! Size large...

I've also had the same feeling, how can those suits work when your face, hands, and breath is still putting out scent! Wind direction is the absolute key to where I hunt. Being higher in a tree seems to help but too high gets dangerous and actually makes for a tough shot angle.

I have used one for a year now and I like it. I am not saying that it is totally scent free but it makes you more aware of your scent. You spent that extra time making sure you wear gloves climbing the stand, using scent free soap, spraying yourself with scent spray, etc. Before I got the suit, I rarely did any of that.

Extreme hit it on the head pretty well. From when I was working a local sporting goods company, I talked to a lot of people looking at the scent lok clothing and found that the majority of them never even took scent control seriously before. The other minority just had $$ to spend smile.gif

I thougt about purchasing the complete outfit once which would have put me out about $400. Instead I purchased 7 hang on style tree stands (75 % off) and a scouting camera for the same $$ as I would have spent on the scent lok gear. With that many stands I can play the wind, and have a better chance of not burning one stand out.

I always recommend having multiple stand locations and adhearing to basic scent control steps before spending $$ on a scent suit. But if you have extra $$ to spend, I can be your personal guide wink.gif

I have used scent blocker for 2 years now and haven't had a deer wiff me yet. I go through everything I can think of to keep my scent down to the lowest possible point. As for the suit, I think that is works just fine... for the first season. Every time you wash it a little of the carbon leaves the suit. I heard that it takes really high heat to recharge the carbon. I used my dryer on the highest setting but I don't think that this works completely. My suit included a jacket, bibs, gloves, baclava, rubber boots, ect. I do all the scent killer stuff and even go so far as taking chlorophil tablets before, and during the hunting season. I wear rubber gloves on my way there and use differant clothing that what I'm hunting in. My point is that carbon clothing isn't perfect. Does it help? Sure. Is it essential? Definately not. Just my 2 cents.

Here's a copy & paste from the HSOforum, about scent-blocker clothing. I'm not sure if the mods will let me post a link.


Do activated-carbon garments really work?

I have been a bow hunter for more than twenty years; during this time I have watched the commercialized hunting arena develop.

Read what other people are saying: Page 1 | Page 2 | Page 3
Got a comment about this article or subject? Let us know!


The extreme commercialization of bow hunting has, in my opinion, resulted instances where hunters have been duped. In fact, I can think of several products that are down right gimmicks and obviously seek to play upon consumer ignorance and slob hunters looking for success shortcuts.

The question has been raised: Can activated-carbon scent elimination clothing really give you an edge against the nose of this animal?
I was once asked, “What do you think is the biggest gimmick on the (outdoors equipment) market is today?” I will warn you up front that my response to the question, which follows, may be a bit painful. Furthermore, I will say that if you do find my response painful, it’s likely that you spent your hard earned wages on the product that I’m about to scrutinize.

Here goes: I believe the biggest gimmick on the outdoors equipment market today is activated-carbon scent elimination clothing that are being marketed under various brand names. You know the ones I’m talking about, so I won’t name names. I’m talking about all of them.

If you’re a bow hunter and believe in the effectiveness of these special garments, hopefully you aren't so angry that you stop reading this article. Because if you read this in its entirety, I promise that you will learn something.

There is a difference between ignorance and stupidity, and I would never dream of calling my fellow bow hunters stupid. It’s the ignorance (i.e. the lack of knowledge) factor that has led many quality and even professional bow hunters to be fooled by the claims made by the manufacturers of scent elimination clothing.

I plan to educate you, not point fingers or spit propaganda. Before I do though, I’ll tell you a bit about myself. I am a biologist by education and received my Bachelor of Science degree from Florida State University. I’ve worked in the environmental protection field for more than ten years.

I have worked with various forms of activated-carbon, the same material that is used in the many brands of scent elimination clothing. Many of you have read articles by authors that claim their scent elimination clothing was pinnacle in helping them tag the biggest buck; without it, the hunt would not have been successful.

What’s new? That is a common marketing strategy used to push new equipment. Bow hunters, despite what gear they choose, are a traditional bunch. Many of us have gained knowledge on how to hunt our query and what equipment to use through word of mouth and testimonials of other perceived more knowledgeable bow hunters.

When Chuck Adam, for instance, talks or writes, I listen and pay attention. I’d be crazy if I didn’t. He is without question a knowledgeable bow hunter and we all stand to learn a lot from an experienced bow hunter like him.

The problem with these scent elimination garments is, unless you have a science background and to an even greater extent, have worked in the environmental protection / remediation profession, you simply cannot posses a clear understanding of how activated-carbon works.

So, as I promised, I am going to tell you how activated-carbon works and why it is my opinion that activated-carbon scent elimination garments are ineffective. Then you can take the information presented here and make an educated decision for yourself.

activated-carbon comes in several forms and is used in many applications as a filtering or cleansing media. activated-carbon can be manufactured from carbonaceous material, including coal (bituminous, subbituminous, and lignite), peat, wood, or nutshells (i.e., coconut shells or walnut shells).

The manufacturing process consists of two phases: carbonization and activation. The carbonization process includes drying and then heating to separate by-products, including tars and other hydrocarbons, from the raw material, as well as to drive off any gases generated. Heating the material at 400–600°C (752-1472°F) in an oxygen-deficient atmosphere that cannot support combustion completes the carbonization process.

activated-carbon comes in the form of a very fine powder, which is impregnated or weaved into the textile fibers of garments. It also comes in a granular form. Both forms are used in various applications including to purify both water and air. Some of the popular drinking water filters and mechanical air filters on the market use activated-carbon as a filter media.

activated-carbon is an extremely porous material with high ratios of surface area to unit weight. One pound of activated-carbon contains up to 100 acres of surface area!

activated-carbon has a particular affinity to organic materials such as volatile organic compounds or VOC’s. Human odor is composed of different gaseous molecules of VOC’s and other chemicals such as hydrogen sulfides, which are absorbed by activated-carbon.

Think of activated-carbon as a common sponge that you would use to wash dishes with. Take a sponge and place it in a cup of water. What happens? It soaks up the water. The sponge, like activated-carbon, has thousands of little pores and channels running through it. When activated-carbon soaks up human “stink” odors, it does so through a process called adsorption.

Stinky gasses (i.e. human odors) are adsorbed into the many micro pores on and within the activated-carbon and are retained there. Now, what happens when a sponge becomes saturated?

A sponge that is saturated with water cannot adsorb any more. Hold a saturated sponge full of water in your hand and you will observe water dripping from it. When activated-carbon in a water or air filter becomes saturated it is called breakthrough.

Forms of activated-carbon


In short, when a water’s or air filter’s filter media (i.e. activated-carbon) becomes saturated with contaminants, the filter is rendered useless and the contaminants contained in the water or air stream pass through the filter. After a while, you will be drinking dirty water or breathing stinky air until the filter is replaced. Makes sense right?

Think of activated-carbon as a molecular sponge. As is the case with any sponge, activated-carbon can only hold or adsorb so much stinky stuff. Once activated-carbon becomes saturated with contaminants, it must be reactivated or replaced entirely.

What do you do with a sponge that is saturated with water? You squeeze it to release the adsorbed water so you can reuse it. Or, you simply get a new dry sponge. Like the sponge analogy, activated-carbon must be “squeezed out” so to speak, in order to reactivate it for reuse.

Now you know how activated-carbon works. Most of the information I just provided can be found on some of the more popular scent elimination garment manufacturers’ web sites.

So far you might be thinking to yourself “Wow, activated-carbon really works”. Well, it does work, sort of.

activated-carbon is a fine filter media, but using activated-carbon as the key component in a scent elimination garment is not a practical application.

Unlike a common kitchen sponge, you can’t just leave it on the counter and let it dry out. In order to re-activate activated-carbon, it must undergo a process called Pyrolysis. To fully re-activate saturated activated-carbon, you must heat it to approximately 800 °C or 1,472 °F, in a controlled atmosphere of low oxygen concentration to reduce the possibility of combustion.

This is scientific fact and is even stated in the U.S. Army Corps of Engineers – Engineering and Design, Adsorption Design Guide, Design Guide No. DG1110-1-2, if you’d like to check it out for yourself. This fact is not however mentioned on any of the popular scent elimination clothing manufacturers’ websites.

One of the most popular scent elimination clothing manufactures instructs consumers to simply place worn garments in a common household clothes dryer for 20 to 30 minutes to re-active the carbon in the garment. The average temperature generated by a clothes dryer does not even come close to being able to generate the extreme temperatures necessary to drive out contaminants absorbed in the many micropores and channels of activated-carbon. In fact, most residential clothes dryers only heat up to a temperature that is well under 200°F.

Those of you, whom use water filters or air filters in your homes, think about it. Why can’t you just boil your filters in hot water or throw them in the oven or microwave for a few minutes to re-activate the carbon filter media. You can’t; that’s why. You don’t own special multi million-dollar pyrolysis thermal regeneration equipment that produces enough heat to re-activate carbon. Therefore, you have to buy new filters every now and then.

Re-activating carbon for industrial uses is big business. Type in the words “activated-carbon” in your favorite Internet search engine and you will see what I’m talking about here. In order to fully reactivate the activated-carbon in one of the many scent elimination garments on the market, you might as well just throw the garment in your campfire, because the extreme heat necessary to re-activate the carbon would likely destroy the garment anyway.

Forgive my sarcasm, but I tend to get irritated when I see good folks getting duped. And as a class, I think bow hunters are a pretty good bunch. So as a product, I think all the activated-carbon scent elimination clothing products on the market are nothing more than gimmicks.

I do not believe, based on sound science, these garments are even effective the first time you use it. Think about it. Each garment would have to be manufactured and placed in a sealed, scent proof bag when shipped and remain sealed on the shelf at retail stores. This is not the case, however.

From the minute the clothing is manufactured, it begins to adsorb “stink” and continues to adsorb “stink” while awaiting an ignorant, misinformed consumer to purchase it. It is likely that the activated-carbon contained in the garment is already completely saturated with “stink” upon being purchased.

Many of the scent proof garment manufacturers somewhat acknowledge this, in an attempt to bring some legitimacy to their product. They recommend that you immediately wash and re-activate garments by placing them in a clothes dryer as soon as the product is purchased. Funny, they also happen to recommend their own brand of laundry detergent that is special made for these special garments.

As I explained above, washing and drying the garment is merely an exercise in futility. At best, the only way these garments could be manufactured and utilized effectively would be if they were designed for one time use. In other words, they would have to be disposable.

The military actually uses activated-carbon suits as a kind of chemical protection garment, but they’re a single-use, disposable garment and not intended for multiple washings.

Here is something else you should consider before purchasing one of these products: activated-carbon’s adsorption effectiveness when used in an air filter application becomes greatly reduced when it is wet. So what happens when you sweat during those humid early season bow hunts? That’s right, your clothing gets wet and becomes even less effective.

A leading manufacturer of activated-carbon garments admits that no laboratory testing has been conducted to determine the effectiveness of the clothing when it is wet from hunter’s perspiration.

So why the craze? Why are so many hunters rushing out to purchase these garments, when the science-based fact is that they don’t work?

As I mentioned earlier, consumer ignorance is one reason. I think another reason is that many hunters so badly want to believe that they can purchase something that will render them invisible to a whitetail’s or elk’s nose.

As I said earlier, many of you have read articles by authors that claim their scent elimination clothing was pinnacle in helping them tag the biggest buck; with out it, the hunt would not have been successful. I truly believe the fact that these hunters who wore these garments while achieving success, can be chalked up to being merely a coincidence. Many of the authors who wrote these type articles failed to mention they were wearing their lucky hat and that their lucky rabbits foot was in their pocket at the time.

All sarcasm aside, I think many successful hunters who wear these special garments fail to recognize that they have been consciously paying closer attention to personal hygiene techniques before every hunt.

You must understand that none of the success story articles that push these special garments are based on science studies. They are opinions; misinformed ones at that.

I’ve talked to a few technical representatives with some of the more popular scent elimination clothing manufacturers and none of them have performed controlled scientific studies to demonstrate the true effectiveness of these garments. However, they claim to have “field tested” the garments. Come on folks. How do you field-test these garments?

It is said that a deer can smell nearly 1,000 times better than humans. You cannot legitimately observe the effectiveness of these garments or read a whitetail’s mind. No one, to the best of my knowledge, has contracted a non-biased independent laboratory or university to demonstrate the effectiveness or ineffectiveness of this clothing.

It is my belief that the manufacturers of these specialty garments know what the results of such a study would show; therefore it would not behoove them to undertake such an exercise. So they just claim the garments are field tested by the product-pushing pros.

As stated earlier: This is just my opinion, but it’s one based on sound science, education and a realistic view of product marketing techniques.

Now you can form your own opinion. Good Hunting.

I think they are waste of money, unless you have plenty. I know of a few old bowhunters who don't buy any of those scent reducing products and also sit and smoke in the tree. They have killed many deer. How? Stay of the trails, and use the wind. Its that simple. It took me a few years to learn this, but once I did, I saved money and seen lots more deer and killed more deer.

I don't think about hunting without mine, since I've starting wearing mine I havn't been winded by a deer in two years, but it goes beyond just that, never wear your huting clothes in the truck on the way to hunt, and obviuosly never in the house. Always store them in a scent free bag along with the other clothes you plan on wearing on the stand. Nothing new here. And always hunt the wind.

You cannot control deer movements, but you can control your scent. Sure you can hunt downwind of trails and smoke in you stand all day long and probably kill deer, small deer. I like to think that if a trophy buck happens to walk on the downwind side of me I still have a chance to kill it without it winding me.

Besides, we all know if you're hunting mature whitetails, there's much more to it than setting up on a well used trail. Larger bucks actually avoid using trails and therefore there movements are much harder to pinpoint. They can show up just about anywhere at any time, especially during the pre rut. Therefore I believe scent control is one of the most important things in hunting whitetails, and well worth the money. Think of all the money we have invested in our hunting seasons: ammo, gun, liscense, clothes, gas, stands, hotel for some people. It would be a shame to have this kind of money invested and have your hunt blown because of something you could have controlled, your scent.

You can pick up a scent control liner for reasonably cheap and I thinks it's well worth the investment!

But for those who can't swing the cost, but are still serious about scent control there are other important steps to take.

1. All hunting cloting washed in baking soda and hung outside to dry before the season and during the season.

2. Shower with a scent free soap everytime before you go hunting.

3. Store clothes in a sealable plastic bag or container for transport or storage. I like to keep a fresh earth scent wafer in the bag.

4. I also spray scent elimination product on my clothes and boots and even my bow before I enter the woods each and every time.

Is there a fool proof 100% money back guarantee way to eliminate all human odor? Probably not, but being more aware of some of the ways to control it will make you a far more successful hunter.

Thats my 2cents

    • the new bait shop is on 169 north over by Sammy's Pizza, Chanticlear Pizza, and Play it Again Sports. 
    • i drive by Ebners place everyday, well most every workday!!!!!! i best look tonight. is this new bait shop taking over at the Ebners old place???????
    • It won’t take 5 years to change the signs, IMO.  2 tops and my money is on 1 more.  I did just get offered a club member deal on a “vintage” Cabela’s cap when I tied placing my order.  The thoughts that went through my head... 🙄   Yes, tried to place my order; use up the last of my points and move on.  Oops, system error, we can’t access your points at this time.  I can see em there, just can’t touch em.  OK, I’ll call back another time. 😤   Still can’t spend money there when I try...
    • I didn't think there ever was such a thing as too many shells! Just saying.
    • yeah, that lakeville FF has been going downhill.  Still, if I need some tackle or something, I'm more likely to go there than across the street.
    • I'm surprised by how much they have merged things together, like a single flyer for sales and whatnot.   I thought the usual way to do this was to maintain two separate brands, to provide the illusion of competition, even though it's really just one place.     I could give a rat's arse what they want to call it, just give me the best prices and put what I want on the shelf and I'll throw my money there if you call it Cabela's or Bass Pro.
    • Seen  the guy again yesterday & asked him if he was finding many & he replied that he thought they were just about done down here already.
    • I bet you're right about Cabelas. As for Fleet Farm, I've been really disappointed in the Lakeville location lately. Over the past year their prices have gone up, they are often out of the item I'm looking for, and they usually are understaffed at the checkout lines.  Perhaps it's just that one store, but I kinda doubt it. Hope they turn it around because I used to love FF and I'm starting to head to other stores now.
    • anybody miss Dozier or Escobar? lol   been a fun ride so far. Its going to be hard to sustain this pace and keep winning like this but I hope they can keep it up.
    • Ok.... So I have to admit that this is something that I have been somewhat fascinated with, but no absolutely nothing about. Here are my main questions... Is there a "Shroom Finding for Dummies" book or something similar that a pure novice myself can pick up? I have read a lot of posts on here that talk about "my spots".... Do morels typical come back the same place every year, or is it just because of the general climate conditions in that "spot" Follow on question.... If they come back the same exact spot, what sort of care is needed when harvesting? Cleaning and prepping.... what are the steps? I assume that it is different for each specific variety of mushroom? What sort of "season" are we looking at? Obviously based on facebook sales posts, the morels are ready now... how long does it last and what about the other varieties? Exactly how dangerous is it for me if I "think" it is one variety and ends up being harmful? Truthfully, this is one of the main items that has stopped me from taking a trek out into the woods. Thanks in advance for letting a newbie in on the trade secrets
