still have questions?

We have answers.
How does reusable absorbent underwear work?

Our absorbent underwear is machine-washable, reusable, comfortable, and discreet — it looks and feels like regular underwear. Our built-in technology absorbs leaks, wicks moisture, and helps control odors — so you can stay fresh and dry while doing your thing. Absorbent underwear can replace single-use disposables for a comfortable solution to periods and bladder leaks. Just wear, wash, and wear again.
Does period underwear feel wet?

Nope! Our underwear is ultra-thin with built-in technology for absorbency without bulkiness. It features a moisture-wicking barrier to help prevent wetness so you stay fresh and dry.

If your underwear starts to feel bulky or wet, or if they notice your flow spreading to the seams, these are signs that it's time for a fresh pair!
Do you have to wear a pad with Thinx underwear?

Our 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.
Which Thinx brand is right for me?

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, is a game-changer for when your period comes back postpartum.
How do I find the right size?

We recommend following the hip measurement to find the most accurate size. Be sure to measure your hips at their widest point, derrière included! We recommend sizing up in underwear styles that fit below the natural waist, or if you're looking for the best fit postpartum. The underwear should fit snugly but not so tight that it becomes uncomfortable.
