If you get your mountain biking kicks from heading down between the tape and racing against the clock on a downhill or an enduro bike, 100% take their standard R-Core jersey, use weight-saving materials and technology to create the race-ready, hard-charging, R-CORE X Jersey. Four-way stretch materials ensure you can move and manoeuvre your bike with unrestricted ease. The polyester blend is also quick to deal with sweat and with an anti-microbial finish, you'll be finishing every run feeling fresh and comfortable. The fit is also focused on delivering plenty of the freedom of movement you need for fast mountain biking. A drop tail adds coverage across the back when you're in an aggressive riding position and contrast taping at shoulder, sleeve and body hem keeps bulk low and comfort levels high. An internal goggle wipe is included for the final shine before breaking the starting beam and dropping into your race run.
