Product Reviews

Lovin it.
This sleeping bag is awesome. I have used it a couple times and every time I go to zip myself in, I just smile and laugh. NO rolling to your side to zip yourself in, or incomfortably crossing your arm over your body. The ease of getting in and out of this bag makes it prime for those late night bathroom runs. Recommend this to anyone looking for a late spring, summer, or early fall bag. Oh and have you checked out the weight... enough said. Review by The Don (AT Trail Name)
