If I was about to buy a new bag, I'd buy a down bag with either a waterproof shell, or waterproof breathable shell.

I'd wanted a Stephensons Warmlite for ages, but never could justify the cost.

Seems most manufacturers copy them in some form or another.

-My next bag will be a high end one, unless I get a more "normal" 700+ fill one on closeout again for a 1/4 the price. My work around for a "normal" 700+ fill bag was to use a vapor barrier liner, and vapor barrier socks (because the vapor barrier liner wore out over time).
