Numark Dryway Liners - RegularPack Size 20 Numark Dryway products are designed to provide discreet, effective protection from incontinence. Dryways have a water-proof backing that wraps around edges to reduce the risk of leakage, an adhesive strip holds the liner firmly in place and a soft, one-way cover keeps fluid away from skin, reducing the risk of skin reaction. The multi layered absorbent core locks in fluid and odour and the channel system disperses fluid evenly throughout the liner for maximum leakage protection.
