Glad you asked, because the Brief does run large. To ensure you will have the right fit, we often recommend ordering one size down from your usual undie size.

You got it, mama. The Brief is a pregnancy must-have: breathable fabric, protection from unexpected leaks (hellooooo, baby on your bladder!), and a classic silhouette to accommodate that growing bump.

Our specially designed Quik-Wick™ lining draws moisture away from the body and helps you feel dry, all day or night.

The Brief features super smooth, seamless fabric, so you stay protected without annoying panty lines.

How Proof Is Made

Proof’s patented Leak-Loc™ technology protects against all of life’s leaks, both big and small. Our undies hold up to 10 teaspoons (that’s 5 full tampons worth!) of liquid. Our manufacturing is OEKO-TEX certified, Prop 65 compliant, and each undie is successfully tested for harmful substances to be body safe.
