The Mystic UL 15 is part of the classic down series of Big Agnes sleeping bags that offer warmth, compressibility and the Big Agnes System which integrates the sleeping bag and sleeping mat. Now even lighter.
Big Agnes says:
Ultralight down fill Big Agnes System bags designed to excel in all conditions
The Mystic UL 15 is one of our most technically designed Big Agnes System bags, using our Flex Pad Sleeve design, a very durable nylon ripstop shell fabric, and super cozy 850 fill power DownTek™ water repellent insulation. This bag combines ultralight versatility with a long line of packable creature comforts. Whether you’re a 3/4 length-pad-carrying, fast fly tent-gram-counter or just gearing up for a trip where weight and packed size is important, this is the go-to bag for you.
Big Agnes' 2019 Mystic UL 15 Down Sleeping Bag is light enough to take backpacking and yet it is more focused on comfort than just the weight. The stretch fabric designed to contain the sleeping mat improves the connection between bag and mat making for a great nights sleep.
The Downtec hydrophobic treated 850 fill power down repels water and speeds up drying time it if does get wet. The lightweight nylon ripstop fabrics are durable and soft to the touch. Vertical side walls help to trap heat closer to your body and the tapered vaulted foot box creates wiggle room for your feet. The bag is well proportioned and quite spacious internally. This would suite people who want that extra space or those who move around a lot as this has the added benefit of the Free Range hood.
To use the full pad sleeve a rectangular sleeping mat is needed and the dimensions of the bag need to match. The material does stretch enough to fit a pillow in too to maximise that comfort.
