The Oakley MOD1 PRO YOUTH is a junior ski helmet that's no joke.Even tougher than the classic version, this pro version features an ultra- shell with injection-molded Dura-Matter construction and EPS foam liner. This helmet resists impacts and bumps especially since it adds a double density foam on the front and sides and incorporates the MIPS brain protection system that reduces the forces of rotation in case of impact. Very comfortable to wear because it is very light, it also benefits from a precise adjustment system and several fixed air vents to keep your head at the right temperature.Finally, this helmet has the magnetic FidLock closure system that allows easy opening and closing of it even with gloves.
