Troy Lee Designs D3 Composite - Corona Red

It's almost impossible to improve on perfection, but with the D3 composite helmet, Troy Lee Designs has absolutely achieved a new revolution in MTB helmets. Developed from the popular D2 chassis, this helmet is equipped with technology that ensures impeccable protection no matter how wild your ride.

Olympic Gold

With a long line of professional cyclists wearing it at events, the D3 composite helmet is currently the only helmet to have historically won Olympic gold in BMX, gold DH Series World Cup and gold at the Redbull Rampage. To say that it is the perfect companion for dirt is an understatement, and with a higher level of protection, shredding the track should be the only plan for the day.

Unparalleled Technology

After being tested in a digital wind tunnel for the perfect helmet, 20 high-flow ventilation and exhaust vents offer the ultimate in breathability to increase airflow and keep your head cool. To improve impact performance, the D3 has added EPS and new head shape, while contoured 3D cheek pads offer an anatomical fit. If the helmet is not enough, it is also provided with two lightweight and contoured visors and a storage bag.
