The MSR MAV 3 helmet is a mid-priced helmet with some high-end features. Modern helmet shells have many sculptured ridges and valleys in them. Most helmets, including some very expensive brands, do not have an impact absorbing EPS liner that follows, and fills in those peaks and valleys. The MAV 3 dual-density liner does fill in those peaks and valleys and this creates improved impact absorption. Safety is key with all MSR helmets and the MAV 3 passes two of the toughest safety standards today. Comfort is addressed with MSR's round-oval shell shape and using top-of-the-line SilverCool wicking material in the interior. This material wicks away perspiration and dries faster than other materials plus it is anti-microbial to help eliminate odors between washes. Shell design features great venting, a strengthened chinbar and large eye port that accommodates most goggles including "over the glasses" types.
