I have found this to be the best sleeping bag for my little boy. After searching high and low for non-synthetic materials for him to sleep in I finally found this breathable merino bag. He never sweats in it and it is easy to get him in and out of it due to the book-opening style of it doing up. It is also great because the zip is around the bottom so it won't irritate his skin as other zips on sleeping bags have which have been near his chin/chest. While it is a bit more expensive than other bags, it is definitely worth the value and it is very quick drying when washing. The little envelope hole at the back and front also make it great for travelling and going out for dinner etc. I will be giving it as a gift many times in the future as it is such a good product!
