Thinx Cotton Brief Period Underwear - Black


Cotton Brief

Holds up to 2 regular tampons' worth.

Comfy, relaxed, breathable, no-stress fit — our Briefs feel just like your fave pair of cozy sweats, except cuter (and period-proof).

How It Works

THINX are made with our signature period-proof tech that absorbs your flow, controls odor, helps prevents leaks, and keeps you fresh ‘n’ dry — all without feeling bulky or wet.

Care Instructions

To take care of your THINX, you rinse first, pop ‘em in a mesh laundry bag (this keeps your delicates, ya know, delicate), then cold wash and hang dry. Don’t use bleach or fabric softener! And yes, the rest of your clothes will be fiiine.
