The Rev It Airborne LL Trousers are packed with features... PROTECTION FEATURES Outer Shell Multi Yarn Polyamide, Polyester and Elastane Round Knit - Made from a combination of polyamide and elastane, this knitted fabric is used to effectively transport moisture away from strategically placed areas for maximum comfort. It\'s designed to wick moisture away from the body and let it easily evaporate, but it also by traps the heat in. Composition 53% Polyamide, 41% Polyester, 6% Elastine ERGONOMIC FEATURES Fit Regular Fit Features 3D Round Knit Technology - Seamless 3D round-knit garments provide superior comfort and technical function for a wide range of athletic activities, including motorcycle riding. The 3D name comes from the texture and shape of the round-knit. Made on a circular knitting machine, seamless garments have superior elasticity for optimal shaping to the body. The virtual lack of seams results in optimal comfort, while also imparting important functionality: fewer seams make the garment less vulnerable for seam breaks, drop stitches, etc., and therefore longer lasting. Those seams that are absolutely necessary are made using flatlock technology, to eliminate bulk. The result is the ultimate in comfort and function. Moisture Wicking Function - Perspiration is constantly moved away from the skin to the outer layer of the fabric, where it can evaporate quickly. This helps you to control your body temperature and keeps you dry and comfortable. Airvent Zone - Airvent zones allow perspiration to evaporate quickly from the body areas that perspire most heavily: the armpit and the back of the knee. The open-knitted mesh structure ensures dryness and comfort.
