The sleeping bag has a comfortable material and is well finished (especially the snaps to shorten and smooth zipper). Other slumber bags have beautiful designs than this, but this is nice and suitable for both boys and for girls. This is the thinnest slumber bag (unlined, only a thin layer of fabric) and we combine it depending on temperature with sleeping bag and body (about 22 ° C) or with body (24 ° / 25 ° C). Since our son does not sleep without a sleeping bag, we have already placed him in very warm temperatures with diaper into the sleeping bag. The only downside: you can the sleeping bag (at least according to washing instructions) do not wash at 60 ° C, which I personally find very important for sleeping, however. Overall, highly recommended and top value for offer!
