Troy Lee Designs - D4 Polyacrylite Shadow MIPS Helmet (MTB)

D4 Polyacrylite Shadow 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. The Polyacrylite shell helps keep the price more approachable while still delivering the coverage riders expect. The Shadow 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: 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:
  • The reigning king of full-face helmets, the D4 range expands with a Polyacrylite model packing the same safety and comfort features as the premium carbon and composite models into a price-conscious shell.

The ideal fetch ball
Our dog is obsessed with these. They bounce well, they’re squishy enough to meet his chewing needs but strong enough to not get destroyed. We do replace them every 8-10 months because after 2-3 20 min fetch sessions almost everyday they do rip. They have a nice weight to them so they’re easy to hurl 20-30 yards.

The best for fetching enthusiasts
We have two lab mix dogs that love to play fetch but also have very strong jaws and sharp teeth. Tennis balls last about 10 seconds. I have used these for several years now and they are the best. They glow in the dark for night fetching, have two holes and are hollow so they whistle when you throw them. The dogs chew them like gum when not fetching and they hold up. They last about a year before starting to tear (this is with almost daily use). These balls are their favorites and get they upset if I use something else.
