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.
