Size and Fit Guide
How to Measure
In order to select the correct sizing, we recommend you take the following measurements using a soft tape measure. If necessary, ask someone else to help.
Waist
Measure around the narrowest part of your torso, usually just above your belly button. Keep the tape snug and level, but not tight. The number where it meets is your waist measurement.
Hip
Stand with your feet together and measure around the fullest part of your hips and buttocks. Keep the tape level and snug, but not tight. The number where it meets is your hip measurement.

Reviews Summary
Generated by AI from 100 most recent customer reviews
Last updated 4 months ago
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.

MHMichelle H.Verified BuyerReviewingLight Leakproof No-Show Boyshort Rose Water / S - Rated 5 out of 5 stars1 week agoAlways 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.
