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.

Jennifer B.Verified BuyerReviewingTeen Super Leakproof® Sleepover Boxer - Rated 4 out of 5 stars6 days agoTeen boxer
The boxer was ok, I love the leak proof, and I don’t have to worry about the sheets anymore. But my daughter doesn’t look the fit. She finds the boxer to be too narrow, if she goes a size up then the liner will be too big.
KKnix6 days agoHey Quinn,
Thanks for the feedback! We're glad the leak protection gives you both peace of mind. We understand the fit challenge - we'd love to help find the perfect size. Feel free to email us at info@knix.com!

Quinn D.Verified BuyerReviewingTeen Super Leakproof® Sleepover Boxer - Rated 5 out of 5 stars1 week agoPerfectly cute AND functional
I bought these for my tween daughter and she absolutely LOVES them. They are comfortable and do exactly what they’re supposed to do. I just ordered her a couple more pairs in different patterns so she has enough to get her through those dreaded few days/nights.

These are perfect fit, soft, fit well., the best even without period. Quality product. The only thing they missed to achieve perfection is pockets!

Edith B.Verified BuyerReviewingTeen Super Leakproof® Sleepover Boxer - Rated 1 out of 5 stars1 month agoLeaked
Unfortunately these did not work for my teen. They leaked and showed on the back and bottom of the shorts. Love the idea and hope they keep working on them, unfortunately these weren’t it for us. (I will spare the viewers a photo!)
LidaVerified ReviewerReviewingTeen Super Leakproof® Sleepover Boxer - Rated 3 out of 5 stars1 month agoCut more narrow and higher inseam than the regular Knix boxers
I bought these because I have the regular boxers and I wanted cute fabrics. The teen boxers are cut more narrowly in the seat and inseam and feel smaller over all. If you buy these to complement your boxer collection, size up and expect the hem to be shorter. KNIX, adults want cute fabrics too. (donating these since they cannot be returned)
KDVerified ReviewerReviewingTeen Super Leakproof® Sleepover Boxer - Rated 5 out of 5 stars2 months agoThese are awesome :D
10/10 would recommend, fit comfortably and haven't leaked
Monique F.Verified BuyerReviewingTeen Super Leakproof® Sleepover Boxer - Rated 5 out of 5 stars2 months agoThe best!
I purchased a pair of these for both my daughters. The blue and the pink striped sleep shorts are cute on and don't look like period undies at all. My girls are 17 & 12 and they both feel confident wearing these on their heaviest day/night.
Julie D.Verified BuyerReviewingTeen Super Leakproof® Sleepover Boxer - Rated 5 out of 5 stars2 months agoFive stars, no notes.
I love these boxers. I am not exaggerating when I say, I get excited for my heavy flow days because I get to wear them to bed. They are so comfortable and absorbent. I am able to sleep through the night with no concerns at all.
Dana N.Verified ReviewerReviewingTeen Super Leakproof® Sleepover Boxer - Rated 5 out of 5 stars3 months agoBest purchase ever
