Pee hole

Such a great product. I would prefer the boy bottoms to NOT have a pee opening. My son is young enough, he just pulls the whole pant down for peeing for now. Having the pee hole makes it less presentable on its own(without an outer layer of clothing). Still totally worth getting.

best long underwear ever

They were well made, comfy and super warm. My son is 8 and we purchased the medium. It was a perfect fit. Definitely will order the next size up for next winter.

They are very soft and he loves them

I got the M for my 9 years old son. He is petite/thin and these fit great(not tight but fitted enough to be a good base layer).

Good product, comfortable and durable

The fabric was lightweight but substantial which was exactly what I was looking for.
