The STX Cell IV Elbow Pads are designed to be light, flexible, and comfortable. With new GeoFlex II technology, these gloves are lighter and 25% more flexible. A new breathable protection system allows air to flow through the pad to help keep you cool and dry. This elbow pad features the use on silicone tape inside the sleeve, which will grip and keep these pads in place. For the sleeve on these pads, STX has included a full-length lycra sleeve which provides excellent comfort and moisture management.
