Hi-Waist Underwear Holds up to 100ml - Light Absorbency

In this review of the Hi-Waist Underwear from Thinx For All Leaks, the bottom line is clear: this washable, reusable incontinence underwear is best for women seeking light absorbency and discreet postpartum protection. The single biggest reason to buy is its capacity to hold up to 100ml (about 1/4 cup) while feeling like regular underwear, so users who need modest leak coverage without pads or bulky garments will appreciate it.

Key Features

• High absorbency core: Holds up to 100ml or about 6 tbsp of liquid to protect against light bladder leaks and postpartum spotting.
• Moisture-wicking top layer: Draws wetness away from the skin so the wearer feels drier and more comfortable during daily activities.
• Washable and reusable: Built to be laundered and worn again, reducing waste compared with disposable options and fitting into a sustainable care routine.
• Odor-control technology: Helps minimize smells so users can stay confident during long days or exercise.
• Comfortable hi-waist fit: The flexible fabric is designed to look and feel like regular underwear for a discreet appearance under clothing.

Who It's For

The Hi-Waist Underwear is aimed at women who need light incontinence protection after childbirth, during exercise, or for occasional bladder leaks, and who prefer a reusable solution over disposables. It suits those who value odor control and a moisture-wicking layer that helps them stay comfortable throughout the day.

Those who regularly need heavy absorbency, overnight protection, or a different cut should look elsewhere, as this style is explicitly designed for light leaks and daytime wear rather than full incontinence coverage or heavy overnight use.
