Innovative comfort - Sierra Designs Cloud 800 Dridown 20 Degree Sleeping Bags - Men's

The zipper-less design of this bag is great for users with broader shoulders. The flap gives the user the ability to adjust the shoulder width to their liking with ease. I did notice the wrap around flap coming open a few times during the night as I move and roll from side to side in my sleep. The sleeping pad sleeve on the back of the bag fits most standard sized square sleeping pads. The feature I like the most about this bag is the foot vent at the bottom of the bag. I sleep pretty hot, and it was easy to stick a foot out of the vent when I found myself overheating. Overall this is a warm, lightweight, and well-made bag for back sleepers.
