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.


Bangor, GB

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