Troy Lee Designs - D4 Polyacrylite Shadow MIPS Helmet (MTB)

D4 Polyacrylite Shadow 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 Polyacrylite shell helps keep the price more approachable while still delivering the coverage riders expect. The Shadow look adds personality, making it a good fit for riders who care about style as much as function. The MIPS-equipped build adds another layer of confidence for riders who prioritize modern helmet technology.

It carries the kind of mountain bike fit that feels settled when speeds rise, but not so heavy or cumbersome that it becomes a distraction on the pedal back up.

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: This is a strong pick when you want a mountain bike helmet that feels at home on everything from rough local descents to destination riding.

Variants / Options: multiple sizes and colorways available; check the selector for current stock.

Key Features:
  • The reigning king of full-face helmets, the D4 range expands with a Polyacrylite model packing the same safety and comfort features as the premium carbon and composite models into a price-conscious shell. Details make the D4 the most coveted full-face in mountain biking, including Mips® C2 brain protection, an air intake system for ventilation, and an unmatched anatomical fit.
  • Mips® C2 Rotational Impact Brain Protection System
  • Advanced Polyacrylite shell construction
  • Front air intake system, with high flow through polymer center and power grid side mesh
  • Collarbone Suspension System

Misinformed dimensions
This product misinformed me of size. It’s 47.235” in length not 48” as advertised. This is just another means of manufacture cheating customers with false information. I did not return as I was just moving into home. I was also in a hurry to finish the installation since I bought three of these not knowing the truth. You can make your own choice but I needed 48” and paid for 48” and got shorted. I used the shipping box to make an template to install brackets that manufacture did not provide.

One out of the four shelves was badly bowed
Exactly what I was looking for but the reason for only three stars is thatone out of the four shelves is extremely bowed, but I only needed three so I just kept them. The quality on the other three is good they are a lightweight wood and anchored to the wall. Well, they seem pretty solid.
