Since most impacts to the head occur while you ragdoll down a slope, POC designed the Receptor Backcountry Helmet to protect against hard shocks as well as the brain-jostling that happens during high-speed crashes. Thanks to the award-winning MIPS technology, your vital gray matter doesn"t get jostled nearly as much as with standard helmets. MIPS technology employs a small plastic piece that breaks during harsh impacts and allows the liner and outer shell to rotate separately, which reduces the stress of ragdolling on your brainTough ABS/PC outer hardshell withstands encounters with rocks and branches, and an aramid barrier between the shell and PC liner further reduces shockEquipped with RECCO avalanche rescue system in case of an emergency
