Just like us, our products are constantly evolving. Launching a whole new period care category over a decade ago was no easy feat—and neither is challenging ourselves to innovate and redefine those same products everyday.
With the launch of Leakproof UltraThin No-Show underwear, we’re changing the period game (again) with new products and absorbencies that feel more lightweight than ever. This is all, of course, with the aim of helping you feel uninhibited on your period, so you can live unapologetically free (from bulky underwear).
Whether you’re a period underwear enthusiast or novice, we’re here to help you find the best period underwear for your lifestyle and flow. Ahead is everything you need to know about our new absorbency classifications and which styles best suit whatever phase of life you're in.
Oh, and psst, if the packaging on your glossy new undies doesn’t totally match up to this guide—don’t worry, we’re working on that.
Lightest Absorbency 🩸
For your lightest period days—you know, when you’re spotting and kind of just want to forget you’re on your period altogether—there’s Light Leakproof No-Show Underwear. This range is designed to be your best friend on light flow days and can be worn with tampons and menstrual cups as backup leak protection. To that we say: go ahead and wear the white pants.
Absorbency: Absorbs 1 to 1.5 tsps of menstrual fluid, discharge, and sweat—which is about the equivalent of 0.5-1 regular tampon.
Styles: Light Leakproof No-Show Bikini, Boyshort, High Rise, Thong, High Rise Thong, Cheeky, and Mesh Thong.
Best for: Wearing solo when you’re spotting, backup protection on regular flow days, and mildly sweaty workouts.
Light Absorbency 🩸🩸

Medium Absorbency 🩸🩸🩸

Heavy Absorbency 🩸🩸🩸🩸
If we had a dime for every time we soaked through bedsheets or our favorite pair of pants, our bank accounts would all have an extra comma. Super Leakproof period underwear styles were designed with heavier flow days in mind—because who wants to wake up early to change their tampon?
Absorbency: Absorbs 6-11 tsps of menstrual fluid, sweat, and urine—which is about the equivalent of 3-6 super tampons.
