You've got questions
Proof undies are designed for comfort and all-day wear.
Our Super-Light, Light and Moderate undies feel just like your favorite pair of regular underwear. Our Heavy and Super-Heavy styles may feel slightly more substantial due to their highly absorbent construction, but they will still feel super comfortable.
Most importantly, you’ll love the extra protection.
In a word, yes!
Our super heavy styles hold 5 tampons or 10 teaspoons of liquid and can replace panty liners and pads as well as replacing or backing up tampons and cups.
If you're unsure about switching to Proof completely, you may feel more comfortable using Proof undies as a back-up for your menstrual cup or tampon.
Panty liners are a thing of the past with Proof. Welcome to modern leak protection - no liners needed!
