it arrived today, it's a present for my son, so it will be opened and tested on 25th Christmas. I will write my review after Christmas, since my son will tell me about his opinion on 25th Dec.
HIGH SPEED delivery. Well... As described. Not 100% cotton but that's good because cotton alone isn't really warming without any polyester, viscose or wool mixed in. I would never wear full cotton underwear in the winter because you will freeze like hell. Good thermal boxers to wear over long johns to give your butt some extra warmth. I would go 1 size up because I bought this boxers before regarding the size table and it was very tight and sexy. Now it's better fitting and more comfy. ReCoMMeND !!!
