The MSR MAV-4 MIPS helmet is the performance leader in value-based off-road helmets and features MIPS (Multi-directional Impact Protection System) technology as well as many other high-end features. What is MIPS? MIPS was developed by brain surgeons and scientists to reduce rotational forces on the brain caused by angled impacts to the head. Adding MIPS to the MAV-4 helmet brings state-of-the-art safety technology other companies charge double the price for. Safety is key with all MSR helmets and the MAV-4 MIPS passes two of the toughest safety standards today (D.O.T. and ECE). Comfort is addressed with the round-oval shell shape and the top-of-the-line SilverCool wicking material in the interior. Shell design features great venting, a strengthened chinbar and a large eye port that accommodates most goggles including over-the-glasses types.
Shell is made of injection-molded polycarbonate.
MIPS technology between the comfort foam and the EPS liner.
SilverCool moisture-wicking liner is removable for easy washing.
SilverCool padding also reduces odor and is anti-microbial.
Nine intake and exhaust vents to keep you cool.
Four eyebrow vents to evaporate sweat before it drips into eyes and goggles.
Wire mesh chinbar vent with foam filter.
Flexible rubber nose / cheek piece to help deflect roost.
Meets or exceeds the ECE 22-05 safety standard and D.O.T. FMVSS 218 safety standard.
Replacement visors sold separately.
Weight: 3.2 pounds / 1480 grams (size Medium).
MIPS is an advanced and efficient brain protection system that provides a secure environment for riders of all kinds. MIPS industry-leading technology deals with "rotational violence" which is found to be the leading cause of concussion and even more severe brain injuries. It mimics the brain's own protection system.
When the head hits the ground at an angle, the brain slides along a membrane on the inner surface of the skull, which reduces the rotational forces transmitted to the brain. The MIPS yellow Low Friction Layer (LFL) sits between the helmet's EPS and the liner. At impact there is a movement, independent of direction, between MIPS and the liner that substantially reduces the rotational force to the brain.
MIPS does not interfere with a helmet's existing safety property, performance or design, adding minimal weight and less than 1 mm in thickness. It's based on more than 15 years of R&D at the Royal Institute of Technology and The Karolinska University Hospital in Stockholm, Sweden.
