THE Thirty3 Composite Helmet

At the speeds of which today’s riders are capable of propelling their machines, extreme protection is mandatory. That’s why t.h.e. created the Thirty3—the world’s first DOT certified helmet designed specifically for mountain-bike and BMX use. We took the protection of our existing full-face lineup and perfected it by making it strong enough for the guys burning dinosaur bones, yet lightweight and breathable enough for stomping pedals at the racetrack or on the trail, then gave it a dose of hot rod-inspired design.

THE Thirty3 Composite Helmet Features:

  • Lightweight fiberglass shell
  • 18 vents / multi-level internal ventilation system
  • Twin Venturi-induction scoops
  • Rear-exit ventilated exhaust system
  • Stainless-steel grill guard
  • Adjustable, replacable louvered visor
  • EVA impact-foam chin-bar liner
  • Integrated goggle guides
  • Moisture-wicking, breathable, washable comfort liner
  • Emergency-removable cheek pads
  • Eject® helmet removal system approved design
  • Exceeds DOT, ASTM 1956, CPSC, EN 1078 and AZ/NZ 206
