The Kelty Cosmic fit my needs perfectly. I needed a bag that packed down as small as possible b/c I have a smaller 40L backpack. The Cosmic easily squeezes down to about 7” round by 10” long. It is also much more lightweight than the standard, old school sleeping bags I was accustomed to.
The Comic is very comfortable and warm in use. In 50 degree weather I wore only a t-shirt and boxers inside the bag with no sheet or liner and was snug as a bug. The mummy-style hood makes a big difference and can also be scrunched up as a make-shift pillow. I would absolutely recommend this high-performance bag for 3-season camping.
