Bollé Trackdown MIPS Mountain Bike Helmet | Purple Gradient Matte - 31627
Description
Built for the demands of trail and enduro riding, the Bollé Trackdown MIPS brings together an eco-conscious construction with rider-first engineering. The MIPS Brain Protection System adds a low-friction layer designed to redirect rotational energy on impact — one of the most meaningful safety upgrades in modern helmet design. An adjustable 3-position visor accommodates goggles without compromise, and the proprietary Opti-Dock system securely parks any size of sunglasses directly on the helmet, eliminating the fumble mid-ride. Extensive ventilation channels keep airflow moving on hard climbs, while the deep rear coverage delivers confidence on technical descents.
The Trackdown arrives in a focused lineup of trail-ready finishes: the aggressive Black Acid Matte and Black Fire Matte suit riders who prefer a blacked-out, no-nonsense aesthetic, while Green Orange and Purple Gradient Matte offer high-visibility contrast that reads well on wooded singletrack. Black Camo Matte and Garnet Matte round out the range with understated texture and warmth. The helmet is offered in three sizes — Small (52–55 cm), Medium (55–59 cm), and Large (59–62 cm) — with an internal fit system that dials in retention for a precise, shake-free fit across long rides.Frame Specifications| Specification | Detail |
