I found this sleeping bag in the camping section of Walmart. I originally bought it for my son to take to his college dorm room in case a friend sleeps over.
My family does a lot of hiking/camping and I thought these would be great for the Summer. Very light weight, soft fleece. We camp in a tent with an air mattress so these would be perfect in the hot weather when regular sleeping bags make you sweaty.
They seem pretty durable, roll up easily, and are pretty compact. I don't think they would be that great if wet. No waterproof lining like a regular sleeping bag has.
Walmart had many different colors to choose from.
These would also be great for kids sleepovers. They do store pretty well just in a bedroom closet. Price was good. I like these a lot.
