Stuffed with 800-fill hydrophobic DriDown(TM), the Sierra Designs BTU -20 sleeping bag features a DriZone(TM) waterproof, breathable membrane for comfort in the coldest, wettest environments. Down is widely considered the best insulation available, but when wet it quickly loses loft and the ability to keep you warm; DriDown is treated to resist moisture. Proprietary process treats each individual goose down plume with a molecular-level polymer so the down stays dry longer, lofts better and dries faster than untreated down. DriDown insulation stays dry 10 times longer, retains 170% more loft when exposed to moisture and dries 33% faster than untreated down. DriZone waterproof, breathable fabric allows moisture to escape while keeping rain out; 30-denier polyester lining fabric is comfortable next to skin. Baffle construction keeps down from migrating, eliminating cold spots. 40 in. zipper keeps weight down and won't let out all the warmth when you're getting in and out of the sleeping bag; locking slider is backed by wide, antisnag binding tape. Snag-free zipper tracks prevent the dreaded stuck zipper by creating a barrier between the lining and the zipper track. Fully insulated draft tube backing the zipper keeps body heat in and cold air out. Ergonomic, nonrestrictive hood cradles your head in warmth; use the drawcords to cinch the hood snug around your head. Includes an internal media pocket for your cell phone or alarm clock. Sierra Designs BTU -20 comes with stuff sack and storage bag.
