Sustainable, comfy, worth the money!
I've been wearing different brands of period undies for around 6 years now. These are by far the best! This is my second pair and I keep telling myself to buy more every month. It is bananas what happens down "there" every month and these undies make everything more manageable. Very comfortable to wear all day long and they hold so much "red stuff". Tbh I do use pads with these due to my fast paced job butttt I go without pads while at home. Small warning- they are made of thicker material. The period hot flashes are going to hit but you'll be comfortable. I know the price tag looks scary but it's absolutely worth the money. The size chart on the website is pretty spot on too.

size up!
I ordered mediums bc I fit in the size range for it and I had some peeps interested by another brand that were a bit too big. They fit mostly ok when I want on my period and tried them on, but once I was bloated they became too tight. Now I'm sick with 4 pairs of period underwear that are slightly too small when I need to wear them 😔
Otherwise, I like how they feel and they seem to hold a good amount of blood. I just wish I bought larges

Comfy well made
These fit my plus size body perfectly. I got a size 3x and I weigh 236 lbs. they didn’t seem to shrink when I washed them. They are the first period underwear I’ve ever worn. Love them so well made. Thank you so much for the exceptional quality!
