THINX Period Underwear Comfort-Stretch Hip Huggers - LeakSafe Briefs

Our review of the THINX Period Underwear Comfort-Stretch Hip Huggers finds them best for people who want reusable, discreet period protection with strong leak resistance. The single biggest reason to buy is the combination of a super absorbent core and a LeakSafe barrier that the brand says holds up to 12 regular tampons' worth of flow and can provide up to 12 hours of protection. These are period panties built to replace or back up disposable products while still looking like everyday underwear.

Key Features

• All-day absorbency: The super absorbent core layer is designed to handle up to 3 regular pads' flow and the overall construction is rated to hold up to 12 regular tampons' worth of menstrual fluid.
• LeakSafe barrier: A built-in barrier helps provide up to 12 hours of leak protection so these can be used as a standalone option or as a backup to cups or tampons.
• Comfort-stretch fabric: The hip hugger silhouette uses silky-smooth, flexible fabric that aims to feel like regular underwear while offering built-in protection.
• Stylish details: Lace and mesh accents are incorporated into the silhouette for a more finished, lingerie-like look compared with basic period briefs.
• Safe materials: The underwear are made without PFAS and are eligible for FSA / HSA purchase, aligning with sustainable and health-focused choices.

Who It's For

The Comfort-Stretch Hip Huggers are a solid choice for people who want dependable leak resistance and prefer underwear that looks and fits like everyday lingerie. They suit anyone replacing disposable pads and liners, or who wants a reliable backup to tampons or menstrual cups for long days away from home.

Those who want a very lightweight, minimal-feel pant may want to look elsewhere: several users report the fit runs small and some find the seam and mesh thickness in the back noticeable. If you need a looser or roomier fit, consider sizing up or a different THINX silhouette.

• Absorbent core that replaces several disposable pads or liners in performance.
