Designed, engineered, and tested by mountain bikers, with close collaboration from 3-time Downhill World Champion Greg Minnaar. The Oakley MTB Helmet DRT5 MIPS (see www.mipsprotection.com) gives you the confidence to master technical descents. It features the BOA FS-1 360° Fit System for adjustment at the neck area. The X-Static technology inhibits bacteria on the textiles, thereby preventing odors. Additionally, it includes a rear mount for securing your sunglasses.
