Waxed cotton is a great material to create weather-resistant and crash-resistant motorcycle riding garments out of, and it has been a great staple material for over 100 years. But, this is not your grandfather's riding jacket. Cortech added Dyneema, the world's strongest fiber, to the cotton weave, making it ultra-tough. Then they added a layer of additional abrasion protection with a Synchromesh liner. A true piece of motorcycle safety equipment in a badass looking chassis. Chassis is a blend of water-resistant waxed cotton and Dyneema, the world's strongest fiber, for great abrasion protection. Fully lined with Syncromesh™ high tenacity abrasion-resistant mesh for added protection. Entire jacket is abrasion, impact, and tear tested. Low-profile, removable shoulder and elbow armor is impact tested. Front opening uses both zipper and snaps for added security.
