Troy Lee Designs - D4 Composite Frames MIPS Helmet (MTB)
D4 Composite Frames MIPS Helmet is a Troy Lee Designs mountain bike helmet built for gravity 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. The Frames graphic gives it a distinct finish that stands out in the pits, on the trailhead rack, or in the garage. The MIPS-equipped build adds another layer of confidence for riders who prioritize modern helmet technology.
That combination of coverage and ventilation makes it a natural match for riders who move between trail networks, rocky descents, and bike-park days through the season.
Why We Like It: it balances mountain bike protection with the kind of ventilation and fit that keeps longer rides from feeling like work.
Why It’ll Work for You: For riders comparing mountain bike helmets, this one makes sense for technical trails, gravity runs, and all-day pedal missions where comfort still matters.
Variants / Options: multiple sizes and colorways available; check the selector for current stock.
Key Features:- Always Evolving. Built with an aerospace shell design and materials, we were able to get the D4 Composite helmet to 1050 grams without sacrificing any strength. Mips® C2 protection system is used to add an additional layer of safety in the event of a fall. For comfort, the D4 Composite routes cooling air through a front air intake system that flows through the polymer center and power grid side mesh keeping your head cooler during the ride. X-static® and XT2® anti-microbial/anti-odor padding keep the inside of the helmet a much nicer place to be.
