Spend a night with Big Agnes and you’ll look forward to sleeping in the backcountry. The Big Agnes System is different than the traditional sleeping bag on top of a sleeping pad. Instead, we unite the two. With Big Agnes, the pad slides into an integrated sleeve on the bottom of the bag, and the top two-thirds of the bag is insulated in the traditional style.

The Mystic 15 is a 775 fill goose down bag, designed for use at temperatures down to -10 Degress C. It takes a 20" x 78" rectangular sleep pad, ensuring a good nights sleep whereever you are. The Mystic comes with it's own stuff sack and packs down to 8" x 6".

Please Note: Big Agnes bags do not come with a sleep mat, this needs to be purchased seperately.
