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

D4 Composite Optic MIPS Helmet is a Troy Lee Designs mountain bike helmet built for mountain bikers who want full-time confidence. 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 Optic treatment gives this helmet a more individual feel than a plain solid option. 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:
  • Always Evolving. Built with an aerospace shell design and materials, we were able to get the D4 Composite helmet to 1050 grams without sacrificing any strength. Mips® C2 protection system is used to add an additional layer of safety in the event of a fall. For comfort, the D4 Composite routes cooling air through a front air intake system that flows through the polymer center and power grid side mesh keeping your head cooler during the ride. X-static® and XT2® anti-microbial/anti-odor padding keep the inside of the helmet a much nicer place to be.
  • Mips® C2 Rotational Impact Brain Protection System
  • 20 high-flow intake and exhaust ports for maximum ventilation
  • Added EPS and new headform shape for improved impact performance
  • Full incremental sizing for greater range of fitment
  • Strategically placed interior chinbar shock pads for comfort and durability
  • Quick-release and contoured 3D cheek pads for emergency helmet removal
  • Purpose-built internal cavities for audio integration
  • Stainless steel chinstrap D-rings are light and strong
  • Includes TLD drawstring helmet sock
  • Exceeds bicycle certifications: CPSC 1203, CE EN 1078:2002+A1:2012 ASTM F1952-15, ASTM F2032-15, ASTM F2040-11

It looks really cool and striking.

Really cool and beautiful watch. Although my specific unit runs 5 seconds fast every day—at first it’s annoying, but eventually you stop caring. 🤣

A Beautiful Timepiece at an Awesome Price!!
Color: Grey, Color: Grey
I have lusted after this watch for four months. I first tried on a similar model (stainless steel band with a green face) in a local jewelry shop (Spitz Jewlers, Walnut Creek, CA, USA). It was "love at first sight," even if I didn't love the white lines on the face from 12-6 and 3-9. At the time, the MSRP was $775. The MSRP has since increased to $795. But I bought this beauty on Amazon.com for only $524.99; after applying the cash-back from my Prime credit card, this watch costs only $498.75. This was "the offer that I could not refuse," to quote from "The Godfather." Accuracy could be better: after only a few days, it is now 7 seconds behind my phone (to which I set my new watch). But I don't really care about that all that much. This is why I rated "accuracy" at 4 stars, but my overall review is 5 stars. My video shows the date changing suddenly at 11:59:59pm, just how I want it; in another photo, you can see that my Seiko changes the date more slowly, which I do not like. This watch is absolutely phenomenally beautiful. If you're on the fence over whether to make this purchase, then I would say "go for it!" You will not find a prettier, more accurate watch at a lower price in ANY store in the entire USA.

Classy and sporty. Great value!
Color: Grey, Color: Grey
Excellent watch for the price. Looks sporty and dressy. More towards dress watch. Blue is dynamic. Strongly recommend blue for sporty feel. I was thinking of aqua terra. This come close to it with a price less than what i would have paid my state tax for omega aqua terra. My only concern is bracelet which i feel kind of OK. Better bracelet design would have made this watch much superior. 21 lug width is awful. Other than that, nothing to complain.

Stunning Gentleman's Watch
Color: Grey
This is my second Tissot watch. It's quite stunning in person. The online photos don't do it justice. It has the look and feel of a much more expensive gentleman's watch which makes this purchase a great bargain. Tissot is a great reliable Swiss made watch brand. My first Tissot watch which is probably more than 20 years old still runs great. Very pleased with this purchase.

Good Tissot Watch
Color: Grey
Arrived on time, in its original box, include a 2 year international warranty, into the box include a book with the Tissot brand history in Switzerland. Algo a second book with a whole catalog of Tissot watches men and women. The watch looks better when you put in on your wrist. The “naval” blue really gives the clock a classy look. The stainless steel workmanship is really good, the metal is bright and perfectly polished. The metal wristband quality is very good, did not have any problem to adjust the size , I went to my preferred clock workshop for this job, they extracted a few pieces of the band to fit to my small wrist size. Have to get used to the butterfly latch, but after a few days, now I learned to open and close it without any effort. The clock it’s very accurate, I’ve been using my Tissot for near a month and it just increased a few seconds per week. I do the setup and check accuracy with my pc clock. In short, It”s a good value watch, nice, good looking, accurate.
