Hi-Waist Underwear for Women, Light Absorbency 100ml - Black 4XL

In this review of the Hi-Waist Underwear for Women by Thinx For All Leaks, the bottom line is simple: these washable, reusable hi-waist briefs are best for postpartum women or anyone with light bladder leaks who wants discreet daily protection without disposable pads. The reviewer found the single biggest reason to buy is the combination of a moisture-wicking top layer and odor-control technology that helps the wearer stay feeling fresh and dry while still looking and feeling like regular underwear.

Key Features

• Washable and reusable: Built to be laundered and worn again, saving on disposables and fitting a more sustainable routine.
• Light absorbency up to 100ml: Designed to hold up to 100ml (roughly 1/4 cup) of liquid, offering reliable protection for light leaks and postpartum spotting.
• Moisture-wicking top layer: The top layer draws wetness away from skin to help maintain a comfortable, dry feeling during regular daily wear.
• Odor-control technology: Fabric treatment helps minimize odors so you can feel confident through the day.
• Comfortable hi-waist fit: The flexible fabric looks and feels like regular underwear while providing coverage that sits higher on the waist for added security.
• PFAS-free construction: The underwear is not made with PFAS, aligning with a preference for reduced chemical exposure.

Who It's For

This product is aimed at women who need light incontinence protection-new mothers recovering postpartum, people with occasional bladder leaks, or anyone who prefers the comfort and environmental benefits of reusable underwear over disposables. The hi-waist shape and discreet black color make it suitable for wearing under everyday clothing, including yoga pants.

Those with moderate to heavy leakage should look for higher-absorbency options or layered solutions, and shoppers sensitive to exact fit should note that sizing can vary; some customers reported a snug fit in larger sizes, so consider trying one to confirm comfort.
