This powerhouse of a bag is packed with 33 oz. of 850+ down, and weighs in at 3 lbs. 8 oz. This efficient cut, -10 degree bag has a full 3-Dimensional down filled collar completely made with Gore Windstopper fabric. The draft tube is also Gore Windstopper fabric and has a stiffening tape. Its V-Block Side Baffle insures perfect down control so that down stays where it is needed most. Caution! This much warmth in so small a package may reach critical mass!
