There are reviews of people complaining that these say knocker but I think thats a bit petty. Who cares that they say that and its pretty clear when you're looking at the pictures of them. These are great unders! Weve had them for almost 2 years now and they still fit him. He went straight to these when he was training and theyve worked great ever since. They have enough stretch that they don't leave marks on his skin but are also tight enough that he can wear them without them falling down. He never seems uncomfortable at all. I would absolutely recommend them and wish there were bigger sizes for my older boys!
