JMT Cairnwrote a review of Big Agnes Mystic UL Sleeping Bag: 15 Degree Down on September 3, 2016
Familiarity: I've put it through the wringer
I used another brand mummy bag (still very comfy) for years. I was looking for something different and found this bag. I had to get a new sleeping pad (to get enough R-Value to warm my backside) and the combo is fantastic. The bag is more like a blanket than a sleeping bag. I have so much room! I do get challenged when putting my sleeping pad into the sleeve but the end results are SO worth the effort. I love than I never come off of the sleeping pad. I recently spent numerous nights in the high sierra and was so warm and cozy. Probably the best nights sleep I have had on the ground in a long while. I highly recommend this bag... might get one for hubby!
