Product Details
Why Choose Our Waterproof Plastic Pants - W99?
Designed for quieter, more comfortable overnight protection, the W99 offers a modern alternative to traditional PVC or rubber-style waterproof pants. With a soft Nylon-Spandex outer fabric, waterproof PU layer, and adjustable leg openings, it delivers reliable backup protection without the stiff, bulky feel commonly associated with conventional plastic pants.
Ultra-Quiet Fabric
Made from a premium Nylon-Spandex blend with a waterproof PU layer, the W99 is designed to minimize the crinkling and rustling often associated with traditional PVC or rubber covers. The soft, flexible fabric feels more like comfortable sportswear, making it a discreet choice for overnight use.
Adjustable Leg Openings
Unlike fixed-leg designs, the W99 features adjustable leg closures that let you customize the fit around your thighs. A closer, more personalized fit helps reduce gaps around the legs and provides added protection against overnight leaks.
Reliable Waterproof Backup Protection
The waterproof PU layer creates an additional barrier over your preferred absorbent incontinence underwear or pads, helping contain leaks and protect clothing and bedding when extra overnight security is needed.
Secure, Stay-in-Place Design
A reinforced elastic waistband and supportive boxer-brief cut help keep the W99 comfortably in position while sleeping. The secure fit is especially useful for side sleepers and people who move frequently during the night.
For Best Results
Wear the W99 over high-absorbency incontinence underwear, briefs, or pads. Adjust the leg openings for a comfortable, close fit around the thighs, especially when wearing thicker or higher-capacity absorbent products.
The W99 is designed as a secondary waterproof barrier and works best when paired with an appropriate absorbent product.
Care Instructions
Easy to Clean: Rinse with water after use or gently hand wash with a mild detergent.
Made for Repeated Use: The durable Nylon-Spandex fabric and waterproof PU layer are designed for regular washing and everyday overnight use.
For best performance, avoid harsh bleach, high heat, and aggressive machine drying.

Us vs Them
Our fabric-like barrier is 100% waterproof yet whisper-quiet.
These are non-absorbent waterproof covers. For best results, pair them with your favorite diaper, pad, or liner.
Yes, absolutely. Plastic pants are designed to be a secondary barrier. When worn over a disposable or cloth diaper, they seal the leg and waist openings, ensuring that any overflow is contained within the pants rather than soaking through to the bedsheets or clothing.

They are much more comfortable than traditional plastic. While the primary job of these pants is to be 100% waterproof to prevent leaks, our high-quality PU (Polyurethane) coating is technically "microporous." This means it allows much more air circulation than old-fashioned, non-porous PVC or vinyl.
Standard plastic pants are usually made of thin, non-breathable vinyl that cracks over time. Our covers are high-performance textile garments. The Spandex/Nylon blend offers:
Durability: They won't crack or stiffen after washing.
Comfort: A soft "cloth-like" feel instead of a sticky plastic feel.
They are completely silent. Unlike traditional PVC or vinyl pants that make a loud "crinkling" noise, our covers are made from a premium 41% Spandex and 59% Nylon fabric blend. They feel like high-quality athletic apparel and move silently under your clothes, providing you with maximum discretion and confidence.
Yes, absolutely. Our covers are 100% BPA-free, Phthalate-free, and Lead-free.
Unlike traditional "plastic pants" made of stiff PVC or vinyl, our covers are made from a premium textile blend of 41% Spandex and 59% Nylon, finished with a high-performance PU (Polyurethane) coating.
