Was glad to get rid of my tidy whites for these comfortable boxers. They are a perfect fit and snug enough to hold me in while playing basketball and soccer. The cotton fabric is super soft and comfortable and the length works well under my uniforms and practice shorts.

These briefs have been perfect for my very picky son. He loves the fit and feel, and he is happy that they have a more grown-up look to them than his previous pairs.
