Yes! All Proof undies offer strong protection, but should be washed gently. Machine wash on gentle using cold water and gentle detergent, and hang or lay flat to dry. Just use, wash, and rewear!

For immediately after birth, we suggest our Super Heavy or Heavy styles, that provide total front-to-back protection with a higher level of absorbency. The Smoothing Brief offers protection for light leaks, along light compression on areas that may need extra support in the postpartum period.

We suggest using Super Heavy or Heavy pairs until your lochia (postpartum bleeding and discharge) has subsided, and then using the Smoothing Brief for a bit of extra protection and support further along in your recovery process.

Our targeted light compression adds support and smoothing to the lower abdomen and back - right where you need it most during *that* time of the month!

The Smoothing Brief is ideal for everyday wear - whether or not you’re on your flow. Bonded edges and high rise with light compression gives a smooth, seamless look under clothing.

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.
