Vegan and Cruelty-Free

How They Work

Our period pants absorb up to 5 tampons' worth of liquid, yet they look and feel just like regular undies.

Our built-in tech works like this:

1. Top layer wicks moisture away from the surface quickly, to keep you dry

2. Our middle layers absorb your blood and lock in your flow

3. The bottom layer pushes liquid back up and keeps you leak-free

It's simple. Just wear, wash and reuse.

Blood, Sweat, Whatever.

Amazed!

These are the first period pants I have tried and I am totally amazed at how well they work and how comfortable they are! I’ve now ordered more! Soo much better than wearing uncomfortable pads and obviously much more environmentally friendly.

Best out there

These are the best out there by a country Mike. The Stryker is great as it’s lace it doesn’t dig in. Would definitely recommend.

The best I've tried

I've tried many different brands of period pants and can honestly say these are the best I've tried. The material is soft inside and outside and doesn't rustle or feel bulky. I bought the bikini style for the lace top, which is so soft (again better quality lace and softer than other brands) - it sits just right on my tummy without cutting in or feeling uncomfortable when I'm bloated. Similarly the bands around the thighs don't cutin and are comfortable. I feel the absorbancy is spot on and I have a really heavy flow but can wear these for the majority of the day before I have to change. The only reason I knocked one star off is the cut of the bikini style around the bum cheeks could cover the bum slightly more. This is just personal preference but I would feel slightly more secure and not as worried about leaks if the cut covered my bum cheeks completely. I have only leaked once at night due to moving around a lot in my sleep.
