There are reasonable places to scrimp and save, but your helmet is not one of them. Keep on course in the Oakley MOD 1 Pro MIPS Round Fit Helmet and reduce your stress level while shredding to your heart's content. The Oakley MOD 1 Pro retains the clean, low profile skate styling of the original MOD 1, but beefs up the durability by switching to an injection-molded Dura-Matter shell. MIPS® and the BOA® 360 Fit System are standard, of course, and Oakley has combined the two to create their unique Skull Matrix system. Features: Construction - Dura-Matter Shell – Oakley's most robust construction uses an injected molded Dura-Matter shell over an EPS foam liner, giving the helmet the highest level of ding and dent resistance. Ventilation -Fixed Venting – Fixed vents in front for goggle ventilation; fixed vents on top for your head. Round Fit – Round fit helmets are designed specifically for rounder shaped heads with added width in the rear and a shorter length to minimize pressure point discomfort from front to back for a comfortable fit. BOA 360 Fit System – A fully adjustable design is engineered to help deliver an exact fit. Skull Matrix – MIPS® and BOA® technologies merge into a unique single system. Skull Matrix is designed to provide a more adaptive fit to help enhance comfort for an improved riding experience. MIPS Brain Protection System – Reduces rotational forces caused by angled impacts to the head. FIDLOCK Buckle System – Seamless magnetic functionality with gloves. POLARTEC Power Grid – Moisture-wicking, removable, washable head liner and earpads. Removable Liner and Earpads – Detachable headliner and earpads offer the freedom to adjust the configuration to your liking, and machine washable for easy cleaning.
