After all, mountain biking progress often means taking a tumble on the way. And with the Youth Mainframe Helmet (MIPS) you'll enjoy the latest safety tech at a brilliant price to performance ratio.Trail-Ready ProtectionThe construction of the Mainframe is of Fox's in-moulded EPS design. This sees a shock-absorbing inner EPS foam covered by a tough polycarbonate outer. Should you crash, always a possibility when tackling technical trails and riding hard and fast, then the EPS foam soaks up and dissipates the damaging forces of a head impact. The tough outer is there to fend off those smaller knocks and bumps you might get when getting a bit too close to tree branches and trail-side overgrowth.Next comes the MIPS brain protection system, a brilliant bit of technology to feature at this entry-level price point.Next comes the MIPS brain protection system, a brilliant bit of technology to feature at this entry-level price point. What is MIPS℃The Multi-directional Impact Protection System (MIPS) is a well-proven technology that reduces the rotational forces on the brain when you're involved in a crash. The forces are absorbed and redirected to prevent them from being transmitted to the brain. MIPS is a Brain Protection SystemRotational motion can cause brain injuriesThe low friction layer allows a sliding movement of 10–15 mm, in all directions, reducing rotational motion to the brain during impactKeep the FlowWhen you're on the bike and enjoying the ebb and flow of ever twisting and turning trails, the Mainframe ensures you don't overheat. With large vents and carefully optimised inner air channels, you'll always have fresh airflow over your head.

This gives a quick and easy way to get the fit just right. And a secure helmet is a safer helmet too. So twist the dial, get comfortable and go rip up some trails. Features:Proven MIPS™ impact protection system reduces rotational forces in a crash byabsorbing and redirecting energies and forces otherwise transmitted to the brainExtended coverage for added safetyOptimized venting with channelled, in-moulded EPS provides efficient coolingRemovable, washable moisture-wicking linerMIPS integrated fit system reduces weight and provides a more comfortable, seamless fitWeight: 390g (Size M)Buy Fox Racing from Chain Reaction Cycles, the World's Largest Online Bike Store.
