Troy Lee Designs - D4 Composite Stealth MIPS Helmet (MTB)

D4 Composite Stealth MIPS Helmet is a Troy Lee Designs mountain bike helmet built for trail 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 Stealth 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.

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 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: It is easy to match to the rest of your kit and easy to live with between rides, which is exactly what most riders want from an MTB helmet.

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

  • 20 high-flow intake and exhaust ports for maximum ventilation

Hopefully This One Will Stop the Critters
This appears to be a nice filter. We have had problems with mice getting in the vehicle through the air vent intake. This is another poor design of the Jeep Grand Cherokee. We had the same issue with an earlier year of the same model and I ended up putting a grill in front to prevent the critters from coming in. I’m hoping this ai filter will be more effective as it is significantly stiffer than other filters. I think the critters are able to lift the end of the filter to slip by and get in the cab. Time will tell, but I do like this one for potentially being more difficult to go by. I would hope Stelantis would fix this, but I won’t hold my breath.
