Leakproof Boyshort

Hey! I'm Kayla and I'm 11! My mom is a nurse and wanted me to be prepared to have my first period, so she got me these. (Bikini's but now I wear boyshorts) This was a lifesaver! I have my period at school and I didn't know and when I went to the bathroom I was able to put on a pad! It saved me from leaking and getting blood all over. It's super comfy and it is very stretchy and breathable. The packaging is also a pencil case, makeup bag etc. It can also be used as a heating pad and comes with cute stickers. You put hot damp/wet face towels and it stays hot for a long time! The heating pad works very well! I would highly recommend these to everyone! There are literally no downsides.

I tried the Knixteen line after finding the women's sizing to be a touch too large for my frame.

Ordered a size L in these and they fit much better. I prefer the overall style of the bikini-type bottoms better but in terms of fit, these are far superior. I actually find that these boyshorts fit snugly and don't move around, which is exactly what one wants with period underwear!

For reference I'm 5'3 and about 125 pounds. If you have a small frame, go for either a size Large or even a Medium in the Knixteen line if you find the regular sizes a touch too large!

I have 12 year old twins. One loves these boy shorts, but she has heavy periods, so wears a pad with them. The other is very petite and live the bikini. She has light periods, so the bikini ones are perfect for her without a pad.

I highly recommend!! I will add, they run pretty small. My bigger gal wears a woman’s size 6 and the boy shorts in large are perfect. My petite size 10 in kids clothes wears the medium bikini, but can also wear the large in a pinch.

I am a woman in my 30s, and find these to be SO helpful! I changed over to a menstrual cup a few years ago due to my concern about environmental waste. But i was still encountering issues with leakage on my heaviest days, and was annoyed I still had to purchase pantyliners in addition to using the cup. No more with these boyshorts and bikinis! I have removed that extra waste from my life, and feel confident and protected when wearing these at work during my heaviest days now! Game changer!!!

I am 87 lb 4'9" adult. My hip measurement is 24 / 25 so I ordered 2 of the boybriefs in small. The fit is very tight on thighs and butt so that my circulation feels cut off making them impractical for exercise. They are thin and otherwise look amazing. Haven't had the chance to bleed in them. Was excited that there is Knixteen since regular Knix sizing is too large for me but I wish the sizing chart accounted for more body types such as curvy and athletic. I've already spent $30+ and have nothing I can use.
