This is for real high speed DH maniacs that will be pushing the limits of the trails and equipment. The SE has the same ventilation as the D2 and way more protection. It's a bit heavier so may not work for racers , but the DOT protection is a must for huckers. One of the lightest DOT helmets, similar weight as Giro mad max. Bunch of funky graphics and color options. usually $500 a steal for $229 at
