Unfortunately, garments that have been worn can no longer be returned due to sanitary reasons. And you know, the market for second-hand underwear isn't all that flash!

So, we will require a brief explanation of the reason for your request.  The trial applies to one worn garment only.

No further refunds, credits or exchanges can be given on any additional worn or washed underpants.

Fabric

Formulated with organic cotton and nylon made from recovered ocean plastics, these underpants whisk moisture away from your body (and plastics away from the turtles!), keeping you dry and "good karma'd" all period long.

So comfortable

I took a gamble buying these online, and I’m really happy with my purchase. They do not feel like period underwear at all. So comfortable, perfect fit and no leaks.

Best overnighters around!

I have the lacy bum in sz10 so as suggested opted for sz12 in the sleep tight and they fit great. These are fabulous, not a leak in sight, even on my first night. I couldn’t tell from the images, and no other reviews seemed to mention it, and I don’t truly quite know how to describe it, but the leg openings don’t have the usual elastic you find on knicker leg openings to keep them in place and you feeling secure. The inner lining meets the outer material lining and somehow the sleep tight stays in place, doesn’t leak and doesn’t end up wedged in places. I don’t know. It’s magic. These are thicker than the other styles but I appreciate the extra protection up the front and back for however I end up sleeping. Highly recommend for overnight!

No Leaks!

I have a very heavy period the first couple of days and I felt very secure wearing the sleep tight. They did not leak and handled the morning "gush". I will be ordering more.
