Troy Lee Designs D3 Composite - Cadence Black/Yellow

This D3 Composite Cadence Helmet from Troy Lee Designs is a multi-award winning full-face helmet and an updated version of their class-leading D2 helmet with functional improvements and next-level safety devices.

Quality is Remarkable

D3 is the only helmet to win Redbull Rampage Gold, WC DH Series Gold and Olympic BMX Gold. The quality of this helmet is remarkable, so much so that riders such as Sam Willoughby, Alise Post, Brendan Fairclough, Aaron Gwin, Mariana Pajon, Cam Zink, Luca Shaw, Steve Peat and Brandon Semenuk refuse to wear any other helmet.

Superior Ventilation

This helmet is constructed from a technologically advanced composite shell with an aerodynamic shell design that has been digital wind tunnel tested and a revolutionary injection-moulded air intake system for ultimate temperature regulation. There are also twenty high-flow intake and exhaust ports for superior ventilation and deep EPS channelling for maximum airflow.

Optimal Comfort & Durability

Features include additional EPS and the updated head form for improved impact performance, full incremental sizing to allow for a greater range of fitment and strategically placed interior chin bar shock pads for optimal comfort and durability.

Quick-Release Cheek Pads

Other features include a removable and washable padded liner with Dri-Lex™ and Coolmax™ moisture-wicking properties, contoured 3D cheek pads that fit anatomically and are quick-release in the event of emergency helmet removal and purpose-built internal cavities for audio integration. There are 2 visors and a helmet bag included with the D3.
