Looks and feels just like regular underwear.
Underx Slimfit Absorbent Underwear are designed with soft, cloth-like materials, a tapered fit, elastic waistband, and reinforced side guards to create a secure, leakage barrier with a discreet, non-bulky fit.
Designed to eliminate leakage, our unisex super absorbent underwear with Xfit technology ensure a custom fit for every body size and shape with dual leak guards to prevent leaks at leg openings.
Our proprietary Xsorb multi-layer technology wicks liquid away from the skin and redistributes into the underwear’s super absorbent core to lock in odor, reduce leaks, and keep skin dry.

Xfit Technology
Xfit was developed in consideration that each body shape and style is different. Underx's unique technology helps eliminate leakage for durable long lasting wear and quality comfort.


Xsorb Technology
Xsorb's tri-layer construction helps underx products to absorb more liquid than a standard diaper, allowing you to achieve a discrete non-bulky fit to maintain a low profile.

Great fit, form, and quality
The sample was much appreciated. I'm an 80 year old who's been using this stuff for the past several years so I know what works and what doesn't. Your product works very well! The briefs fit perfectly and really worked as advertised with the xfit and xsorb features. I will be signing up for a monthly subscription. Thank you!
