With a 3-Dimensional down-filled collar, sturdy draft tube, and expertly designed hood, the Antelope is both secure and luxurious. Made from the lightest and most compressible Gore Windstopper™ 830 fabric, it is also the most waterproof option for sleeping bags. The entire collar and draft tube are constructed with this fabric for unbeatable protection.
