Leakproof Girls Boyshorts

 

We think our 'Oh No' Proof Boyshort Period Underwear is pretty great. These cute boyshort undies are made with super soft lycra fabric and carbon cotton, meaning you stay dry when it matters the most.

Our seamless design lets you say goodbye to underwear lines, and the super thin built-in panty liner (sucks up 1-3 tsp of moisture) is invisible even under tight clothes. 

Girls boy shorts that have got your back.

 

Overview text:

Boy oh boy, do we have the period boyshorts of your dreams! These comfy girls’ boyshorts give you protection from menstrual leaks, odor, moisture, and underwear lines. These are no period panties of yesteryear — this cute and active cut is perfect for girls who want to look and feel good during Auntie Flo’s monthly visit. 

Our miracle boyshort undies are leak-proof and can absorb up to 3 teaspoons of blood — that’s the equivalent of 2 regular tampons! Plus, they’re totally seamless (can we get a hallelujah for no VPL in your cute summer dress?). 

We especially love how these nylon and spandex boyshorts wick away any moisture and sweat, keep you feeling fresh and odor-free throughout your period. 

Our boyshorts for girls are lightweight, cute, and 100% comfortable. Buy your first pair today, or surprise a teen with a gift they’ll love.

    Very satisfying from the fit to the delivery.

    It works best on light to medium days.

    Super convenient

    Have had for a couple months now. So far so good! If they last, will definitely be better than pads - comfort wise and environmentally

    Great for Menstrual Cup Users!

    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!!!
