The POC Fornix Backcountry MIPS Helmet is ultra light weight and will protect your noggin from heavy impacts. The MIPS System protects your brain from rotational forces that happen in oblique impacts. When an impact occurs the outer shell rotates around the inner helmet to give you more protection. An Aramid bridge in the core of the helmet spreads out the impact over a larger surface. A dial in the back will help you get your fit dialed in just right. On the top of the Fornix Backcountry you have adjustable vents that will keep you cool on the hike up, and goggle vents keep the air moving to prevent your lenses from fogging up. FEATURES: In-mold helmet with EPS liner Internal MIPS system Aramid bridge reinforcements for structural stability and dispersion of impact energy Adjustable ventilation Goggle vents evacuate steam from your goggles Goggle clip Size adjustment system for a comfortable and safe fit
