Thank you Steve, but I guess this Rioyalo sleeping bag is a very very budget option...
People claiming on false advertised features. Temperature rating shows 5-35 Celcius not Fahrenheit, which means 41-89°F.
And I will not be camping in temps higher than 20-30* F. In the Colorado Rockies (say, above 9000 feet), you can expect frosty nights at any time. I would not venture out, even in midsummer, with less than a 20-32*F bag.
And for the price, it certainly cannot be goose or duck down filled, that is going to be really cold in the mountains.
I am not so low on a budget
And considered on purchasing smth from AEGISMAX or Kelty with the same fill power.
And Teton Sports sleeping bag would be much intriguing alternative for a budget sleeping bag that this Rioyalo. Teton Sports is also US manufacturer, and the second is Chinese I suppose...
