Troy Lee Designs - D4 Composite MIPS Stealth Helmet (MTB)
Troy Lee Designs - D4 Composite MIPS Stealth Helmet (MTB)
D4 Composite MIPS Stealth Helmet is a Troy Lee Designs mountain bike helmet built for enduro and bike-park riders. The D4 platform is known for downhill-focused coverage and a locked-in feel when the terrain gets steep and fast. The composite build gives it a balanced mix of feel, durability, and value for regular riding. In the Stealth colorway, it brings a strong visual identity without losing the performance-first focus of the helmet. The MIPS-equipped build adds another layer of confidence for riders who prioritize modern helmet technology.
The fit is aimed at riders who need their MTB helmet to stay composed on technical descents while still feeling comfortable during transitions, climbs, and longer days outside.
Why We Like It: it fits the way a modern MTB helmet should: secure, ventilated, and ready for real terrain.
Why It’ll Work for You: It works well for riders who split time between trail loops, enduro stages, and lift-served laps and want one mountain bike helmet that feels ready for all of it.
Variants / Options: multiple sizes and colorways available; check the selector for current stock.
Key Features:- 20 high-flow intake and exhaust ports for maximum ventilation
- Added eps and new headform shape for improved impact performance
- Full incremental sizing for greater range of fitment
- Strategically placed interior chinbar shock pads for comfort and durability
- Quick-release and contoured 3D cheek pads for emergency helmet removal
- Purpose-built internal cavities for audio integration
- Stainless steel chinstrap D-rings are light and strong
- Includes TLD drawstring helmet sock
- Exceeds bicycle certifications: CPSC 1203, CE EN 1078:2002+A1:2012 ASTM F1952-15, ASTM F2032-15, ASTM F2040-11
