The 509 Altitude 2.0 is a fiberglass off-road helmet built for snowmobiling and dirt riding, with a hand-laid shell, nine intake vents and four exhaust vents, and a moisture-wicking removable liner. It uses a quick-release chin strap and an intermediate oval fit, and the liner and cheek pads can be swapped to tune the fit. At about 5.45 lbs it is heavy for a dirt helmet, and it carries DOT only, not ECE or Snell. Riders who want a broad range of shell sizes and easy liner washing tend to like it; those counting grams or wanting MIPS should look at the Altitude Pro Carbon Fiber instead.

Owners rate it well overall, praising the venting, the comfortable liner and the wide size range. The main complaints are weight and the DOT-only certification.
