Reviews Summary
Customers say these boyshorts are exceptionally comfortable, feeling like wearing nothing at all. They appreciate the soft, silky fabric and true-to-size fit that doesn't ride up or create panty lines. Many find them perfect for daily wear, workouts, and under work clothes. Users frequently mention the peace of mind they provide for light bladder leaks and period backup. The no-show design works well under leggings and tight clothing. Some note the protective area could be larger, and a few experienced sizing issues with leg openings being too loose or needing to size up for comfort.

    Very satisfied

    I’m very pleased with these undies. Fit well and if I do pee a little after a sneeze, the built in pad will get it

    Wonderful Fit

    Excellent protection for sweaty work. I am lucky enough to have found these several years ago. They have changed my life for the better. They are the only underwear I ever wear nowadays. The fit is wonderful and the way they soak up sweat while working in the yard or walking my dog is brilliant! I highly recommend them.

    Great for teens!

    I’ve loved these boy shorts for years after being recommended by my sister-in-law. My teenage daughter also loves them now that she is in the phase of her life.

    Always love the boyshorts!

    I always love my Knix boy shorts and wish they would carry more of them and in more colours. It seems like they don’t make as many of them anymore, so I was pleased to find this pack left on my size. I find them try to size, but they usually are a little snug to start and need to form to your body.
