worry-free postpartum protection

Our absorbent underwear are machine-washable and reusable to replace single-use disposables for a comfortable solution to period and bladder leaks. They come in discreet designs that look and feel like regular underwear. Just wear, wash, and reuse. They absorb leaks, help to control odors, and wick moisture — so you can stay fresh and dry while doing your thing.

Nope! They're designed with lightweight built-in technology to absorb without bulking up or spilling over, and our moisture-wicking barrier helps prevent leaks, so you stay feeling fresh and dry.

Every pair of underwear features our signature, absorbent built-in technology, so there’s no need to use pads or liners! Plus, they're best at helping to prevent leaks when they fit close to the body.

Thinx for All Leaks is your solution to bladder leaks during pregnancy (especially in the third trimester, when your expanding uterus puts additional pressure on your bladder!) and for postpartum bladder control. Thinx period underwear, on the other hand, are a game-changer for postpartum period bleeding. Your period can often come back heavier post-birth, too, so our super absorbency styles of Thinx postpartum underwear help to protect against leaks as you’re adjusting back to your flow.

We recommend following the hip measurement to find the most accurate size. Be sure to measure your hips at their widest point, derrière included!

Thinx underwear are simple to care for: just machine wash with the rest of your laundry on cold before your first wear, then after each use. Your other clothes will be fine! Steer clear of fabric softener and bleach. And, last but not least, hang dry your undies. For your Thinx for All Leaks undies, you can tumble dry on low or hang dry.
