I love these! They’re so soft and feel great. They do run a little large but I don’t mind that! So comfy! Going to buy another pair! Best thing that Knix has to offer!

Purchased the pink stripe, blue stripe and the black one. Love the fit and feel more secure for the 3am wake up run to the bathroom! Covers enough for lounging in. Will definitely be wearing for a long time. Great for travel.

Amazing work!
I was a little skeptical on how these would work on a truly heavy flow overnight and I'm truly shocked. This was my first foray into period underwear and I'm so happy I did it. Night 1 and 2 were conquered without any worry of leaking. I'm excited to keep using this and hope these hold up after several wears
