Great

Lucy July 20, 2022

It is confortable and doesn't look like granny underwear. It doesn't work well for sleeping but for the day it goes great.

Buy now!!!

Marissa June 17, 2022

I am shocked at this underwear! With the tampon shortage I just tried these that were recommended to me by my sister and HOLY SMOKES this is a game changer. I am so excited that I never have to buy a pad or tampon ever again! Price is so reasonable! Go buy these now!!

Amazing

Rachel September 1, 2022

I live by these Heavy Briefs on my heavy flow days! I have tried a bunch of other period panty brands, but Unders has been the only brand that's worked for me. All of the other brands were either too uncomfortable or not well equipped enough for my heavy flow days. Best of all, they're SO AFFORDABLE! Thank you Unders by Proof for giving me confidence on even my heaviest of flow days

MUST-HAVE: Unders by Proof!!

Macy July 13, 2022

These are just what I needed - affordable, comfortable, and don't make me feel gross when I'm on my period. Would highly recommend to anyone with a period or for ANY time of the month! The material prevents bunching in the crotch and holds up well with a no-show lining. No complaints from me!

Never Have to Worry About Bleeding Through!

Becca July 4, 2022

I love these undies because I can wear them all day and never have to worry about bleeding through, even with white pants! Because of Unders, I can go about my day and focus on what needs to get done rather than worry if I'm leaking through my pants! They're so comfy and so breathable, it doesn't even feel like I'm wearing anything!

These are a gamechanger.

Melanie July 26, 2022

This underwear feels like every other kind of regular underwear but even softer! You can barely feel that there is a layer in the middle to catch and absorb but it does such a great job of drying and making you feel clean and supported all day. I have never had a leak with these and I would even wear them with white jeans that's how much I love them!

Nothing compares!

Ella April 26, 2024

The material of these is AMAZONG. I love that they are the stretch no show type material!! They are the only period panties I can tolerate the feel of. I actually wear the light version of the Unders panty as my daily panty just because after my 3rd c section, they help hold my pouch in :oh, and yes they do hold 2 tampons worth and will not leak.. even at gushing speed. Lol

Needs to be bigger

Moyar July 17, 2022

I like how lightweight is feels, but the pad in the middle needs to be longer. I got an XL and the pad doesn't reach the front so there was some leaking. I don't know if you have to have a smaller butt, but the design is odd. I would recommend for a light flow or spotting.
