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.

  • 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.

Classic and expensive looking
Color: Vintage Green, Color: Vintage Green
Love this addition to our bust collection! The dark green really looks like old metal. A bit on the small size but true to specs. This is still a great looking bust but it's just not very large. I suggest 14-16 inches or over if you want something more substantial.

Dermatologist recommended it!
Size: 1.3 Ounce (Pack of 1)
This is my 11th order of this product. I originally started using it a few years ago when my dermatologist recommended it during a period of hormonal acne. I’ve been using it ever since. I have very sensitive skin that usually reacts to almost everything, either with redness or breakouts, but I can use this cream comfortably without any issues. It is very gentle, deeply hydrating, and has become a permanent part of my skincare routine. It is definitely worth the price. Even a small amount provides excellent hydration and it lasts a long time. I also love that it has a natural ingredients and is fragrance-free.

Game changer.
Size: 1.3 Ounce (Pack of 1)
I moved out to Arizona back in 2020 and shortly after that, I became a reptile. My skin would become flaky and peel and I tried several different types of facial creams and lotions with no luck. I went to a dermatologist who recommended CeraVe, and it did help my skin to an extent. It took care of the flakiness, but I would still see the dryness, especially when I looked in the mirror up close. I recently was on Google doing a search and came across this brand. I thought I’d give them a try and though I was skeptical, my skin has not looked this good in years. My skin feels smooth, hydrated and NO greasiness. I highly recommend this product.

Wonderfully effective and slightly bougie

I have dry not so sensitive skin. I love the way this smells and feels on my tired parched face.
