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.

BULKY & BUCKLING HANDLES
Color: Tan
The handles are bulky, and the leather buckles where you normally would hold it which is very uncomfortable. If you try to use the shoulder strap, the handles don't come off and get in the way when holding the purse against your side. Unfortunately, I first used it well past the eligible return date. I'm so disappointed. I would not recommend this product.

easy to access interior with many different pockets
Color: Desert
The back pack is awsome. It's soft, elegant and fits a lot of items...can be used in lieu of small carry on. I liked the openness of the interior area. The inside utility clear pouch was only 1 pouch, not 3 like the video. But I like it better with 1 pouch which leaves me options for larger items. The shoe pouch can be used for other items instead of shoes, if your interested.
