I'm currently in the market for a 20 degree down bag. So far I'm trying to choose between Western Mountaineering's "Ultralite Super" 20 degree down bag or Mrmot's "Helium" 15 degree down bag. Both bags are 850 fill.
I've only heard super things about WM products. I believe that their 20 degree rating is conservative so I could get away with using it in mildish winters. I also hear the durability of WM bags are great.
I don't know a whole lot about Marmot bags. They're roughly the same price, so thats not really a factor. I want a bag that is going to be durable and at least as warm as its rating.
Heres the other important factor, I'm allergic to feathers. The Marmot bags claim to be hypoallergenic. They clean the down.
I called the maufacturers of the WM bags and they said their bags are "not specifically hypoallergenic".
I know WM is top of the line so you don't really need to praise them for my benefit, but can anyone speak to Marmot's bags?
Thanks!
