Bought the larger/warmer sleeping bags. Unpacked easy, fluffed up well by shaking it out a bunch (important to fluff up before use after being compressed). Daughter used one in tent on an inflatable mat, she had 1 layer of clothes plus 1 camp blanket and wore a hat and wool socks at night - stayed warm even with temps at 5c overnight. I was in a hammock and was glad for my extra blanket to wrap around myself in the sleeping bag - I had extra warm clothes, wool socks and a hat as well. The sleeping bag was comfy, and I loved the hood part. Definitely need to wear dry warm clothes/layers in such low temps but great overall.
I used this sleeping bag in wild camping. Very comfortable, warm and very light. The hood is very comfortable. I gave a 4 because the zipper gets stuck in the material from time to time. You have to go there delicately.
This sleeping bag (large version) fits me perfectly (I am 6'2" and a bigger guy). It's warm, weighs very little and compresses down very well. I had some questions and experience excellent customer service from this seller. Highly recommend . I really like the foot room and the hood for colder nights. You won't find a better sleeping bag for this price.
Just back from my test camp. Only about 12°C was nice and warm. I love the roominess of the bag. Very light and packs down very small.
