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

D4 Carbon Frames MIPS Helmet is a Troy Lee Designs mountain bike helmet built for enduro and bike-park 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. The Frames 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: 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.

Much much better than the standard sock
Size: X-Large, Color: (001) Black / Black / Castlerock
These socks are superb. Lots of padding in the right places, snug where it should be snug & loose where you don't want it to bind. They are marked with an 'L' for left foot, & 'R' for the right foot (it makes a difference in the fit being perfect. They stay up on your heel & don't slide down

4 lefts vs 2 rights
Size: Medium, Color: (001) Black / Black / Castlerock, Size: Medium, Color: (001) Black / Black / Castlerock
I ordered a set of three. I ended up with four left socks and two right socks lol. Granted it doesn’t matter unless you’re OCD. JEEZ. Love the socks but not the attention to detail the sock company did on matching left/right marked socks.

Hold up to tough wear - definitely recommend
Size: X-Large, Color: (001) Black / Black / Castlerock
These are my teens favorite socks. We've ordered multiple sets. Given that he tends to wear then as slippers I am really impressed with how they hold up. The extra large size is great for bigger feet. They wash well and I didn't notice any shrinkage, fading or pilling. This set is going to college with him.
