Warm, compact and Ultralight!

I paired this bag with a sea-to-summit silk mummy liner and two sleeping pads and was plenty warm with low temp of 27 on first night and 25 the second night! Definitely recommended!!


This bag is nice and light, packs down to a small footprint and kept me toasty warm in sub 40-degree temps. This is a great bag, well designed, great quality. Love the bag. My feet are generally cold and I had zero problems. This is the best sleeping bag I have owned. Sorry, I forgot to take pics of the bag on our backpacking trips.

Best bag!

This is by far the most comfortable bag I have ever used. I slept in it again last weekend at 11,000 ft and loved it. The hood is fantastic and fits easily over my head and eyes. I am 6'2 and have the long version. Definitely worth purchasing!

I love this bag!

Got it for month-long backpacking trip on the PCT and found it to be perfect. It was soft and warm on the cold nights, and comfy to sleep on top of for the warmer nights. Compresses easily and very light-weight to carry in my pack. Zipper is great, no catching or snagging. Great bag all around.
