The Zenith series down-filled sleeping bags are designed and built for high-performance. The design features a contoured hood and mummy shape which help seal in warmth. For added heat retention, the Zenith boasts an insulated chest and zipper baffle — keeping the warmth in and the cold night air out. An included compression stuff sack allows the light-weight down bag to compress smaller than other bags so you will have plenty of room in your pack for other gear and essentials. The Zenith is offered in multiple sizes and temperatures to accommodate most people. Keep warmth, comfort, and weight savings at the top of your priority list — try the Zenith on your next backpacking adventure!
