THINX Comfort Stretch Hi-Waist Period Underwear – All-Day Absorbency, Leakproof Protection (Up to 12 Tampons), Black, 1X

Meet THINX Comfort Stretch Hi-Waist Period Underwear

Designed for real life, THINX Comfort Stretch Hi-Waist blends a flattering silhouette with delicate lace and mesh details in a silky, flexible fabric. It aims to provide reliable protection while staying comfortable enough to wear all day, from morning meetings to evening plans.

All-day absorbency without the bulk

This underwear can hold up to 12 regular tampons worth of flow, thanks to a super absorbent core. It can also manage the equivalent of up to 3 regular pads. Individual results may vary, but the design prioritizes a smooth, unconstrained feel that tops your everyday basics.

Leakproof protection for long days

The built-in LeakSafe barrier is designed to help provide reliable protection for up to 12 hours on a single pair. Whether you’re at work, on a trip, or tackling a full schedule, this option can serve as a complete replacement for disposables or as a backup to tampons or menstrual cups.

Soft, flexible comfort you can wear with confidence

The fabric moves with you rather than restricting motion, creating a comfortable, underwear-like fit. The product is PFAS-free and eligible for FSA/HSA purchases, aligning with a sustainable, reusable approach to menstruation.

Real-life possibilities

Imagine long flights, busy workdays, workouts, or weekend adventures where protection feels natural and unobtrusive. The design emphasizes comfort and simplicity, so you can focus on your day rather than the page you’re on.
