Proof reviews and discussion

I tested these out and was shocked (in a good way) how much blood they hold. I've tried other brands in the past and have leaked more than once. In total transparency I normally use 1 super tampon every 2-3 hours on my heaviest days. I slept in the heaviest version of the underwear and used a tampon as well. On my last day i did not wear anything except these. I recommend.

I bought Proof Undies for my heavy periods, and they really worked! I was skeptical at first and thought it would feel like a diaper, but they are actually soo comfy and soft. There are so many styles, including no-show thongs you can wear with leggings or tighter pants. Now I use them when I'm not even on my period to protect from sweat or discharge leakage. Works like a charm, and sustainable too! Love the product and what the brand stands for.
