The ProFlex 525 Lightweight Padded Knee Sleeves feature a flexible foam knee pad and a low-profile spandex sleeve design for enhanced flexibility and comfort. Inspired by athletic knee pads, these lightweight knee sleeves are built for movement. Soft strapless nylon spandex fits and flexes comfortably under or over clothes, providing workers with an alternative to more traditional bulky knee pads. For enhanced breathability and comfort, the back of the sleeve features mesh paneling to improve airflow and reduce sweat. Pads are made of an EVA (ethylene-vinyl acetate) foam and abrasion-resistant fabric to prevent scratching or marring on both tough and delicate surfaces. Pads feature a flexible interlocking TriHex pattern, designed to freely move with the knee's natural movements and provide protective support.
