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

D4 Carbon Stealth MIPS Helmet is a Troy Lee Designs mountain bike helmet built for gravity 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 Stealth 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.

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 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.

Key Features:
  • MIPS brain protection system, reduces rotational forces to the brain in some crash scenarios
  • Three shell sizes to more accurately fit a variety of head sizes and rider ages, improving overall safety
  • Removable snap-in, washable comfort liner with Coolmax® and Dri-lex® moisture-wicking materials
  • Super light titanium D-rings save weight and have increased material tensile strength
  • CPSC 1203*, CE EN1078*, ASTM F1952-DH, ASTM 2032-BMX. *Varies by regional standards

Husband loves it!
Color: Dark Gray, Size: Large
Husband loves it so much we purchased a few different colors. No shrinking while washing, true to the size and color, soft yet warm. Great price! For a guy who prefers only hoodies, he now chooses these shirts when we go out for dinner or an event.

Might be great, if the outdoor temperature drops
Looks nice and it fits. But giving you a review of what it feels like, you will have to wait till it gets below 65 degrees.

Great value watch with all the basic functions.
This is a solid watch for the money. I think if you are looking for a training watch that doesn't break the bank, this is a good option. I looked at a ton of options, and I know there are some even cheaper entry level options, but this Ironman was a little bit of a step up in appearance and quality. To me it's worth it to get this over something in that $20 to $30 range. The Ironman was more stylish and less bulky than a lot of those options. This watch has a nice sized face that makes it easy to see without being so large that it's too much. There are some of these entry level sports/military watches that are just enormous. I'm not a huge guy so this was a much better option. One thing I am really liking is how flexible the strap is. The material has a nice give to it making it a very comfortable watch to wear. I've had some watches in the past where the bands were just too stiff and made the watch very uncomfortable. It's easy to understand and operate. I didn't even read the manual and had everything figured out after 5 or so minutes. Unless you are really going to step up and get a GPS smart watch in the $200 and up range, this watch is a great option.
