Happy customer!

These period pants are a life saver. They for comfortably, are breathable and most importantly they give me the confidence to know it doesn’t matter how heavy I flow I won’t be leaking anywhere.

absorbent but baggy

I've found the Wuka pants brilliant for daytime but struggled at night a bit, so I got these. I ordered my usual size but they feel too big, they moved around when I turned over and I did not feel confident that they wouldn't leak. Overall I was disappointed and will continue to lay on a towel as well, which is what I wanted to avoid. Absorbancy is veryb good but i didnt feel that i could trust them alone.

Genius!

I have PCOS so I have a heavy flow. I wish o discovered these sooner. No more trying to sleep in one position so the pad doesn’t move, no more checking the sheet in the morning. Will be buying for my daughter when she gets her periods.
