Perfect for winter or summer camp!! Compact and easy to pack up!

Purchased for daughter for Drum Corps International audition. Sleep quarters are on school gym floor. It was perfect for winter and she said it will be great for her entire summer tour!! Super soft, light and warm. Compact and easy to pack up too.

Lightweight but warm enough

I used it tent camping at the end of October in the 40s. I was never cold despite how thin it was but to be fair I had brought an extra lightweight blanket. I can’t say how it would perform under 40 degrees but you should be fine to at least that temp without another layer. It’s light, thin and packs easy. Great for the price.
