Used this sleeping bag camping in Yosemite. Kept warm and was comfortable. I liked the idea that I can join another sleeping bag together for more room.
The most I can get it to measure out to is 37 inches wide and 76 inches long from tip of arch to bottom and 65 inches not including arch where it goes straight across from the bottom . If your 6 foot most of your upper body will be sticking out of the bag.
This AWESOME Sleeping Bag states it is for 15°F temperature outside.... And I completely agree it kept me warm in about 20°F but so toasty I had to up-zip it a bit and let some cold air in I can't wait to actually test it during some winter weather!!!
I'm 5'7" and I have to fold my legs to be fully covered in this sleeping bag. It's been 27 degrees out at night and I do feel the coolness when I'm in it. Have to pile a few coats over the bag. If you're 6' feet tall this bag will be at your chest or belly button. If I decide to keep it I'm going to have to get a liner to really keep it at the supposed 15 degrees.
