    So very comfortable!

    I love these briefs. No lines, smooth and of course, comfortable. The liners absorb really well and are comfortable.

    I truly recommend these boybriefs.

    The right size makes the difference

    Originally I bought medium and it was totally wrong. So I went up to large and they are perfect! The one complaint I have is that they can not be dried in the drier. Something I didn’t see stated in the description.

    Boybrief v Boyshort

    I usually wear the French cut but wanted to try something different. Purchased both a boybrief (leopard print) and a boyshort (pink). Both very pretty. More importantly, both were extremely comfortable! Especially the boybrief! Would definitely recommend both!
