This bag was used twice and neither time was it slept in. Used as a blanket because it wasnt cold enough outside… The Eider is the roomier version of the Widgeon, which was originally designed for the successful American K2 expedition in 1990. Permanent collar with EX facing to prevent breath condensation from entering the bag. Continuous baffles let you position the down where you need it. 3D contoured hood wraps a layer of insulation around your head. Generous draft tube prevents cold air from seeping past the zipper.

Tuck-stitch construction hides the baffle threads and prevents moisture from wicking through to the inside. Includes storage bag & stuff sack. As for the Nextec shell fabric.
