The Rokker Rokkertech jeans are constructed of a new innovative material, created by Rokker. The UHMWPE (ultra-high-molecular-weight polyethene), which is twice as strong as steel, allows these pants to be constructed of a single layer for unbeatable wearing comfort. Most motorcycle pants have a Kevlar liner which compromises wearing comfort. Not the Rokkertech! The UHMWPE core is wrapped by cotton thread which give the pants a real denim look and feel. You won't feel the protective material but rest assured, it will do its job when you go down in a slide. The single layer construction also means improved airflow compared to other riding jeans.The Rokker Rokkertech has pockets for optional hip and knee protectors (D3O armor sold separately). There are no rivets on these pants which could scratch the bike. Regarding the fit, the Rokkertech is a so called straight fit: slim legs with a tapered fit.
