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 you comfortable so you can get up the next morning, hit the trail, and conquer 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 MTNDRY™ (mountain dry) down that repels water, dries out fast, and recovers it’s 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.
The shell of the bag is 20D micro ripstop that won’t tear or let the down escape. The soft nylon lining is comfortable against your skin. Taped, anti-snag zippers are easy to close from inside or outside of the bag. And if that wasn’t enough, we’ve also added a convenient interior zip pocket to help keep track of your wallet or keys.
If it’s your first adventure or you’re an experienced backpacker, the ALTOS Ultralight Down Mummy Bag is perfect for you—especially in the colder seasons. And get this, as an added bonus, because it’s so lightweight and compresses down into its stuff sack, the sleeping bag is designed to fit perfectly in all TETON Sports internal frame and ultralight packs.
