Our fully contoured design maintains full and even loft of the 900+ fill down in the head and shoulder regions.

This system also serves as a backup in the event of a zipper failure; a deadly proposition at 60 below zero.

Well... that’s the idea. If you’re chasing the coldest temperatures in the world, this is the bag for you.
