Out of stock


When you’ve been out hiking, through rain or shine, nothing’s more inviting at the end of the day than warm, dry gear. The ALTOS Ultralight Down Mummy Bag is TETON tough for adventuring in all types of weather. Made especially with dual-stage MTN-DRY down that was designed to keep yo ucomfortable so you can get up the next morning, hit the trail, and coonquer your next adventure. Starting at the top of the bag there’s a 3-piece hood that contours your face and can cinch down tightly for added warmth. The ALTOS is filled with our dual-stage MTN-DRY (mountain dry) down that repels water, dries out fast, and recovers its fluff quickly so you can enjoy the comfort and warmth of down with a recovery time that is quicker than even synthetic fills. The full-length zipper draft tube keeps the warm air in and the cold out.
