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

Fabulous Lasting Chew Bone
Flavor Name: Bacon, Size: Large - 3 Pack
I can no longer get the Deerhorns they loved, so I have been buying these. They are so excited when I open a new package and give it to them. They like all sizes. They place their feet on the handles and hold it, making it easier for them to chew on them. They are a little less expensive if I visit a local Walmart store. The problem is that they are often out or not stocked.

my dog loves it, but is chewing small, jagged shreds off of it
Flavor Name: Bacon, Size: Large - 2 Pack
My dog loves this bone and he is able to easily hold it in his paws due to the shape. He is half bernedoodle and half bloodhound quite large 75 pounds and is a very aggressive chewer. My only concern is that he is biting off small pieces of what I believe is plastic since it’s the nylon one. I know he’s probably ingesting some of the pieces. Is this supposed to happen?

Excellent chew option!!!!
Flavor Name: Bacon, Size: Large - 2 Pack
My pups love these! They are able to easily hole them with their paws and they must like he taste as these are their.favorite ‘bones’. They also last along time and do not ‘splinter’. My 12 year old loves to throw it on the air and play with it!
