Our heavy flow Seamless Period Pants are ultra-thin, super smooth, and truly invisible. Designed with soft, lightweight nylon, they are super stretchy, and comfortable and can be worn seamlessly under anything. The breathable fabric keeps things nice and cool, and of course, our signature built-in tech absorbs moisture and prevents leaks.

Fit true to size. Due to the high elastane content, they can feel a little tight upon first use, however, they will loosen slightly after the first few wears.

    So, you'll be diverting waste from landfill, while wearing light-weight, quick-drying, and super-smooth undies. Win-win!

    I love these! So comfy. I feel sexy and comfortable. Truly the best period pants I’ve had. So glad I came across these via my local sustainable shop.



    I have several different period underwear from different companies and these are most definitely the most comfortable and feel the least like diapers!

    So comfortable, super absorbent and leak proof, they are so discreet too! it feels like I’m free bleeding! I love them! I need more!


    York, GB

    So soft and comfortable. Much better to wear under tighter clothing than the other types. Would recommend.

    Others have dug in, these are great and so so much more comfortable than disposable pads!
