Troy Lee Designs - Lightning D4 Carbon MIPS Helmet (MTB)

Lightning D4 Carbon 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. Carbon construction points to a lighter, more premium feel that works well for riders chasing high-end performance. In the Lightning 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 gives riders a stable feel on rough descents without turning every climb into a chore.

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.

Good quality, water resistant
Size: 52 inch, Color: Black
Feels thinner than the one I had before this which was the same company and model. Still good quality and value for the money. Fits well and looks good. Is water resistant and black is the true color. We’ll see how sturdy it is over the years.

Good cover for the price
Size: 58 inch, Color: Black
I’m very happy with this grill cover so far. It fit my grill really well without being too tight or loose. The material feels sturdy and weather-resistant, and it seems like it will hold up well over time. It was easy to put on and gives good coverage and protection. Definitely worth the purchase

Good quality for a great price!
Size: 52 inch, Color: Black
Very nice grill cover! I thought it was going to be a thin piece of plastic, but I was surprised when it came and it’s actually a substantially thick layered cover. The inside has a thermal layer I didn’t expect. Even the Velcro tabs on the sides are thick! I feel like I really got my moneys worth! I just have a regular gas grill that gets little use. I noticed this year there was rust on it in spots, so I thought a cover would help prevent any more rusting. I think this will definitely help my rust situation, plus it looks neater with a cover. Very happy with this purchase!

Great product
Size: 58 inch, Color: Black
This cover is excellent quality and fits my grill perfectly. The material feels durable, and it’s fully waterproof, which protects the non‑stainless steel parts from rain and moisture. Overall, it gives me great peace of mind knowing my grill is well protected.

Very nice and priced right
Size: 48 inch, Color: Heavy Duty-Black
Although this cover is slightly larger than my grill, it's heavy duty and should last a long time in the weather. Installing was a breeze, and the velcro straps help secure it in place better than my last one. This truly is a nice cover and appears to be able to withstand anything thrown at it. Nice product, 2 thumbs up!!
