Moonstone™ 15 Goose Down Mummy Sleeping Bag (Long)
See it in Action


Warmth in Cold Conditions.
Thermal Reflective
This technology helps regulate your temperature by reflecting & retaining the warmth your body generates, while dissipating moisture & excess heat to keep you comfortable.


Cushioned, blocked, shielded and shaded.
Resist Rain
and Stains
This rain and stain barrier resists light rain and stains, keeping you clean and protected. Omni-Shield delivers protection from the outdoors where you least expect it but need it most.
In addition to 800-fill goose down and the Omni-Heat lining, which traps and recirculates your body heat while providing breathability and down fill, several thoughtful design details work together to help cancel heat loss: a draft tube along the zipper—which is glow in the dark for ease of use in the dark—prevents it from becoming a cold spot, and a face gasket cinches down to keep crucial head heat in. A stash pocket near the zipper top is the perfect spot to store your cell phone. A trapezoid toe box provides plenty of room for foot comfort. Featuring a smooth yet strong shell fabric and a minimalist, utility-focused design, the Moonstone compresses down into a miniscule 7”x14” stuff sack to take up minimal room in your pack.
