Great super lightweight bag that packs up super small, without a giant price tag.


  • Lightweight
  • Warm
  • Packs up super small


  • Lightweight ripstop material may not prove that durable

Warmth: I purchased the Moonstone 15 to replace my synthetic bag in my attempt to go lighter and smaller. I was skeptical at first that this bag or other down bags I have checked out would keep me warm in freezing temperatures. The down loft just did not compare to my down duvet on my bed or the quantity of insulation required in a comparably rated synthetic bag.

Boy was I ever wrong. I tested the bag for three consecutive nights in the back yard at 15° F wearing only my skivvies. I slept on my Therm-a-Rest CampRest mattress in a chintzy Coleman dome tent. Snug as a bug I was.  I am confident the bag will keep me warm to 0° F! There were no cold spots or drafts.

Fit & Comfort: At 6'3" I ordered the long bag and I fit fine. My feet did not feel confined thanks to the shape of the toe box. The bag is a bit tight in the shoulders making final zipping and cinching the face gasket shut just a touch difficult. I am an average build and by no means have broad shoulders.

Moisture: Once zipped up the bag warmed up quickly thanks to the reflective lining. I started to wonder if the nag was breathable or if moisture condensation on the bags shell would result. When I awoke, my tent was soaked, but the bag was dry. I cannot yet attest if moisture may accumulate over many nights and days of sub freezing temps.

Packability: This bag packs up extremely small which will allow me to ditch my old, heavy pack for a newer, more lightweight pack.

Features:The Omni-heat reflective lining in this bag coupled with how lightweight and packable it is seems to set it apart with other comparably priced bags out there. .

Construction & Durability: The lightweight ripstop material seems a bit thin. Again I have only used the bag for three consecutive nights so far. None of the down feathers poked through the material. The bag appears to be very well constructed.

Here's what other sites are saying:

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.
