The positioning and thickness of the gusset varies across styles, depending on absorbency. These styles have extra back coverage and fit true to size, but for the best fit, we recommend going up one size so you have a little extra room.
Wear the Heavy and Super Cotton Brief styles on your heavy flow days. The Cotton Boyshort has a fitted leg for cozy overnight protection.
We have heard from parents in our community that they love wearing Thinx period-absorbing underwear postpartum! We identified the underwear styles in our collection as most suitable for this time. Thinx can provide leak protection you can trust through postpartum and when your period returns. For the best fit during postpartum, we recommend sizing up. Before using any new product, you should check with your doctor to see when our products can best work for you. Learn more about how new parents use Thinx for Postpartum.
Thinx is machine-washable and reusable period-absorbing underwear — providing a more sustainable alternative to single-use disposable products. Thinx underwear for periods is designed in a range of absorbencies, from lightest to super, to support every stage of your flow. Every pair of Thinx period-absorbing underwear features our signature, innovative built-in technology — a moisture-wicking top layer, an absorbent core layer, and an outermost leak-resistant barrier. Check out our How Thinx Work page to learn more.
Every flow is different! You can wear period-absorbing underwear for as long as your flow will allow. And of course, the style you wear also plays a factor, as some underwear styles are more absorbent than others. We measure our underwear for periods by absorbency, with our highest absorbency styles holding up to 5 tampons worth of flow. For some customers, they will last the whole day, and others may need to carry an extra pair of Thinx period underwear as a backup. If you feel damp or notice your flow spreading to the seams, that is an indicator you should change into a fresh pair. We suggest bringing along a resealable bag, pouch, or wet bag — so that if you do need to change out of your first pair of Thinx undies, you've got a place to put them. If you're unsure which styles to start with, we recommend taking our Know Your Flow quiz.
We recommend following the hip measurement to find the most accurate size. Be sure to measure your hips at their widest point, derriere included! We recommend sizing up in underwear styles that fit below the natural waist. Check the fit details of each underwear style via our size chart. The underwear should fit snugly but not so tight that it becomes uncomfortable.
