Shop Thinx Teens

Fresh Start Period Kits are multiple pairs of our best-selling underwear for cycle-long protection. If you're looking for a period pack to kickstart your teen's menstrual cycle, our period starter kit has got you covered. They're perfect for stocking up even more of on your teen's favorite styles, too! Fresh Start Period Kits are only eligible for return or exchange as a unit.

See fabric & materials for information specific to each style.

Our underwear is not made or treated with PFAS.

We recommend starting with 3-5 pairs so you'll be protected for their entire period without doing extra laundry.

Thinx Teens should fit slightly more snug than your regular underwear to provide maximum protection from leaks. We recommend following the hip measurement, as most of our styles sit on the hips. Be sure to measure the hips at your widest point (derriere included!) Take a peek at our handy sizing chart to get the right measurements for the perfect fit.
