Not Diapers—Solving Your Embarrassment and Keeping You Fresh and Comfortable
Many older men experience issues with prostate enlargement. As men age, especially after 30, the glands near the urethra in the prostate can begin to proliferate due to hormonal changes. By age 50 and beyond, prostate enlargement often becomes a problem that affects urination. This can lead to symptoms such as slow urination, frequent urination, dribbling, nighttime urination, or a feeling of incomplete emptying.According to the National Health Service data, more than 50% of men aged 50 and older experience prostate enlargement, and this percentage increases with age. Due to issues like dribbling and incomplete emptying, Japan has designed special leak-Safe Pants for older men. These garments are absorbent, odor-eliminating, and lightweight, allowing older individuals to stay fresh and improve their quality of life.

Rapid Odor Elimination
The inner absorbent layer can hold up to approximately 140cc of liquid.

Quickly Eliminates Unpleasant Ammonia Odors!
Utilizing advanced scientific technology, the deodorizing fibers in these pants absorb and transform foul-smelling components into less offensive substances, effectively removing unwanted odors. As shown in the image, the ammonia residue concentration (ppm) is significantly reduced in the specially processed "advanced polymer fibers" used in these pants compared to regular materials and untreated fabrics (30/1). This immediate effectiveness ensures that you won’t have to worry about unpleasant smells leaking out, even when you're on the go.
Side Leak Prevention and Comfortable Fit
The absorbent layer is sewn vertically along the waistband, both front and back, while the three-dimensional side design prevents liquid from leaking out.
Although the front opening can be opened, the construction of the absorbent layer means that the front panel cannot directly expose the genital area.
Safe Pants are made from 100% cotton for a skin-friendly material.
The just-right elasticity and thickness provide a comfortable touch and feel.
