Glamping at it's finest

Don't get me wrong, this bag is cumbersome and enormous. However, it is by far the warmest and comfiest bag I've ever owned. Perfect for sleeping in my truck during the winter waterfowl season!

One of my best purchases

Love this sleeping bag. The non-constricting design is great for staying comfortable. The bag kept me very warm, almost too warm, in 40 degree nights. Would be great for those cold cold nights. Would recommend pairing with the sleeping pad. Very satisfied!

Sleeping in a cloud

We purchased two to replace our older ones. We zipped the two bags together - king-size double. It is suitable for hot, warm, and cold weather. It is the best buy we have made. The inside is so smooth and warm - like floating on a cloud.

Roomy and Warm

The Klimt Big Cottonwood Sleeping bag is fantastic. I am a side sleeper and toss and turn all night, I rarely get a good nights sleep in my old mummy bag. This sleeping bag has more than enough room for me to toss and turn all night and stay warm while at it. This pairs perfectly with my Klymaloft XL sleeping Pad.
