Comfortable and absorbent
Very comfortable and absorbent. Happily surprised there is still the ability to use a pad with it.

Wedgie Issue
Liners don't go far enough back. Making it very uncomfortable.

Ok but not very comfy or secure feeling
I like the material, but the padding on the crotch part is really big and bunches up and doesn't really sit well.

Could be awesome with some fixes.
Ok, so the boy short version is my go-to only because the long version, which I would prefer, actually pulls the pad I wear over the gusset, away from my body, constantly. Please integrate the absorbent layer into the fabric so this won’t happen. In addition to that, the giant gusset in the long version is way too bulky and sticks out. I don’t mind the larger gusset, but it needs to be more practical. One more thing, the shorts part of the underwear would be made with some type of absorbent material because there are many times I will bleed over one side or the other and then I trash my pants and potentially the furniture I’m on at the time.

Loving these!
My partner gave me a pair they no longer use and I’m so in love. Had to buy more! Best menstrual undies I’ve tried out of 4 other brands. So comfortable and cozy. Easy to clean.

Improved from originals
Fit is the same as my regular underwear with tomboy. 5'4" and 160 athletic build and I wear medium. The larger, more absorbent pad is great and so much nicer than the originals of this style. Very comfortable as all their materials are. Easy to wash and care for. Highly recommended
