We bought this summer sleeping bag on the recommendation of a friend, because our son in the sleeping bags that we had, was very night sweating, even when they should be sleeping summer. The material is pleasant, he seems to feel comfortable in it, because he no longer starts to cry when we put him there. I especially appreciate that you can upgrade the sleeping bag by a sleeping bag for the winter and that you can dry it in the dryer. This is not so with many other models. Can only recommend the sleeping bag!
