Our patented Leak-Loc® technology has multiple layers that draw in moisture and help lock in leaks. The Quick-Wick liner helps pull moisture away from the body and into the super absorbent core.
Our undies are designed to fight odor, helping you to feel fresh and dry. Plus, our styles are machine washable and reusable, and can be worn as normal undies.
Here’s a quick absorbency breakdown:
- Light: Holds up to 1 regular tampon or 2 teaspoons
- Regular: Holds up to 2 regular tampons or 6 teaspoons
- Heavy: Holds up to 5 regular tampons or 8 teaspoons

One of the biggest benefits of switching to Unders® is that leakproof undies are machine washable and reusable, so you can wear them again and again.
Depending on your chosen absorbency level, our leak-resistant and leakproof styles can hold anywhere from 1 light tampon to 5 regular tampons' worth of liquid.
You may also feel more comfortable using Unders® undies as a backup to a menstrual cup or tampon.
