Almost perfect

Fits well and is very comfortable. Absorbent and easy to clean. I love that it can be dried in dryer. After a few washes I noticed the elastic at the top has folded over on itself and looks stretched. Not sure if this means I got a size too small (although they fit really well and don’t dig in or anything) or if maybe they are not 100% dryer safe. They still fit well, just a visual thing that bums me out.

Wish they weren’t period underwear…

I love these things. I actually get a little excited when I get my period now because it means I get to wear the most comfortable underwear I own. Seriously, I wish you made a version of these that fit exactly the same but were just for daily wear. They’re so comfortable and they keep me feeling pretty dry even on my heaviest days. Full disclosure I also use a menstrual disc. Could I wear them on regular days, sure. But am I going to, no. I’ll just keep saving them to wear at my most uncomfortable time of the month as a special treat!

My daughter loves them. Comfortable and good protection. And they can be put in the dryer, which is fabulous!

I like them

Very comfy to wear at night. I have very heavy flow, so use a few booster liners inside
