Most Helpful Positive Review Great Sleeping Bag
It packs down extremely small. Just make sure to add ten degrees to the rated temperature - that's closer to the comfort level of the bag. A care suggestion, especially for an extremely light down bag like this, would be to keep it unpacked as much as possible. Once you get to camp, unfold this baby so it has time to decompress otherwise it's really wrinkly and lacks volume, which decreases insulation.

Incredible bag

by TJ, from OR, United States Written on October 11, 2023
Crazy light and packable but warm. Get the large size if you’re wide shouldered. I am 6’1 210lbs and had to return my regular size as it was claustrophobic. I recommend more room too if you toss and turn like I do when backpacking. Used in WY for backpacking hunts and loved it. Not too noisy either

Very good bag

by Allie, Verified Owner from Taiwan Written on November 30, 2020
I took this bag bike packing and it was exactly what I wanted - packable, extremely light, and most importantly, warm. It packs down extremely small (just gotta work it into the smaller stuff sack, starting with the wider part) - not much bigger than a Nalgene bottle, and very light (just over a pound!)
