Slide into the Mystic.
Put on some music before turning in and catching some refreshing sleep with the Big Agnes Mystic UL 15 Degree Down Sleeping Bag. It has plenty of warmth for three-season backpacking trips and will also crush it on winter hut or yurt trips. The Mystic ditches bottom insulation in favor of an integrated pad sleeve, which saves on weight and boosts warmth. As a result, the Mystic weighs less than 2.5 pounds. Don't think for a second that it sacrifices warmth, though—it's loaded up with 850-fill DownTek water-repellent down that's arranged in Insotect Flow vertical baffles. The baffles conform to your body for increased warmth and comfort and use internal gates to keep the down in place so you don't have to deal with cold spots.
Not only is the down water-repellent, but the Pertex ripstop nylon fabric is so tightly woven that it prevents moisture, like tent condensation, from seeping in. The rectangular shape means you have a few sleep-position options. Drafts tremble in fear before the Mystic thanks to the no-draft collar, wedge, and zipper that keep them locked out and your heat locked in. And, as a final touch, Big Agnes designed the Mystic so that left-zip bags can connect to right-zip options, letting you and all your stuffed animals sleep together comfortably.

- Q & A
Light as a feather.
- Familiarity: I've used it once or twice and have initial impressions
First of all, this bag weighs nothing, and stuffs down to nothing, which is a huge bonus if you're trying to save weight and space in your pack. The mummy shape feels way roomier than a lot of other mummies I've used in the past - I didn't feel constricted at all. I did use the integrated sleeping pad sleeve for the Q-Core that I have, and it worked like a charm. No sliding around in the middle of the night!
I used this bag on a 25 degree night and definitely woke up a few times feeling a bit cold, but it's really important to mention that I run cold, and temperature ratings ARE NOT comfort ratings. That being said, I would continue to use it for 25+ temps.
Warm and Toasty!
- Familiarity: I've used it several times
This bag is super soft and has a great hand to it. My favorite feature has to be the integrated pad sleeve on the bottom. I am not usually a big fan of mummy shaped bags but with the footshape toe box this bag didn't feel like a mummy at all. It kept me warm all night, and usually, my feet are the first area that get cold and with the way the footbox is designed it helped to keep my toes nice and toasty all night. I really loved how big the top was too, super easy to get in and out of and it felt almost like a blanket instead of a sleeping bag.
Can this bag accommodate a 25" wide pad (2.5" thick) at all? Is says that it takes a 20", but I'm curious if it could be stretched to be used with the Thermarest XTherm Large.
