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

D4 Composite Frames 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 composite build gives it a balanced mix of feel, durability, and value for regular riding. The Frames graphic gives it a distinct finish that stands out in the pits, on the trailhead rack, or in the garage. The MIPS-equipped build adds another layer of confidence for riders who prioritize modern helmet technology.

That combination of coverage and ventilation makes it a natural match for riders who move between trail networks, rocky descents, and bike-park days through the season.

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: For riders comparing mountain bike helmets, this one makes sense for technical trails, gravity runs, and all-day pedal missions where comfort still matters.

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

My bag strap pulling out.
Color: Camel, Color: Camel
I got this bag as a gift from July and started using it in the middle of September for work. I love it but the left strap is pulling off. I am very disappointed.

Comfy and supportive
Love it! Very snug and supportive. I am 5‘6“ 188 pounds. I am wearing a 34H and it fits perfect. Will definitely be adding more colors to my collection. Hopefully they add the HSIA Delia collection that are similar to these, but have printed options.

Good value, fantastic fit
Color: Grey Purple, Size: 38D
Very comfortable lingerie, gives a smooth look under clothing. Very satisfied with this purchase. I have purchased bras at higher price point, these are comparable. Good quality and value for the money.

Very Good strong material
I love the bra but story time, I initially got a 38DDDwhich is or was my size however I wore the 38DDD all day at work (RN) and the bra did hurt my sides like the sides were possibly too tight and digging into my ribs BUT the support was amazing and the minimizing was PERFECT I looked almost 2 cups sizes smaller in my opinion but I figured something was off so I ordered a 40DDD got those and the side digging wasn’t there but I lost a little bit of support maybe or I could have just done the straps wrong because it was a quick try on but overall I love the slimming effect and the material is soft and I truly appreciate this bra. The material is STRONG not cheaply made very beautiful over all. This is a good quality bra once I figure out the correct size . I ordered another 38G to see if I noticed a difference and a 40G to see if my cup size is wrong all together (which is what I think it is more so than the band size) I tried another brand and the 38 band was find the cup was too small in 3 different brands. Guess I’ve gained some weight but overall even with the pain for the side digging I could tell this was a GREAT bra. Just measure yourself correctly lol
