Klymit KSB 20By: David on 20 November 2017I was initially dubious about the design of this sleeping bag but decided to try it out, and I’m glad I did. I bought this sleeping bag for overnight to multi-day hikes and wanted something that was warm, lightweight and able to be compressed to a small size without breaking the bank. The flexible baffles keep the bag snug around the lower part of the body without being constricting. I tend to move around when I sleep and with other sleeping bags I am forever getting tangled. I found the Klymit bag moved with me and not once have I been tangled or constricted. The sleeping bag is fairly light weight and stuffs down to a small size. A couple of good shakes once out of the stuff sack lofts out the sleeping bag. I used this bag up on Mount Feather Top in the snow where it got down to -6 degrees. I slept in a merino base layer and was kept nice and snug without feeling the cold. At 1 degree no base layer is required. On another trip where it only got down to 12 degrees I was starting to get uncomfortably. I wouldn't use it in temperatures much higher than this. I also bought a Sea to Summit Ultra Sil Compression sack which compresses the sleeping bag into a very manageable size. I think this sleeping bag performs above its price range, I am very happy with the purchase. 5 Stars for durability however I have only had this sleeping bag for 6 months. The build quality appears to be of a high standard thus my judgment is based off this.
