Best boxer briefs ever!

David Kim

Super comfortable boxer briefs - it has a silky/soft feel to it that exudes a feel of luxury. I have tried other high-end boxers/briefs before like MeUndies but can definitely say that these are a lot more comfortable.

COMFORTABLE!

Durfey T.

These have solved my problem of a trunk/brief that is functional, comfortable and does not ride up. I have big thighs and other brands no ride band wears out quickly. Bought one to try and after first time wearing, order four more. Best part is the flex style can be worn as a compression type short for working out, so you get two in one function!
