For all-day comfort and coverage. Free Samples!
Underx Slimfit Adult Diapers are designed with soft, cloth-like materials, an 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 ensures 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 it into the underwear’s super absorbent core to lock in odor, reduce leaks, and keep skin dry.
Once you've ordered, tried, and loved your free incontinence products, see our incontinence products for men.
Xfit Technology
Xfit was developed in consideration that each body shape and style is different. Underx's unique technology helps eliminate diaper 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.

I received a free sample of xl underwear, after thinking about what all this means I tried them on. Different feeling then what I thought for sure they are soft and comfortable. Now for the test after drinking lots of water I waited until the urge was too much and just let go. Not only did they work without leaking my skin was dry. You’ll know your wearing them but they work without problems.
