I bought the neck warmer, because I've always frozen in the neck when I was with the baby outside. When wearing me was all nice and warm, but not at the neck and breastbone. For this product is perfect! I'll drag him under the sweater / Sweat-Sirt, so nothing can knubbeln and am well protected against the cold. Found him after a long search on the internet and since then are all the other products that I had bought for this purpose in the closet unused.
