Troy Lee is an industry leader when it comes to graphic design, and even more so when it comes to helmets and safety. The same great attention to detail and expansive dynamic feel that goes into creating a piece of artwork is also implemented into crafting these pieces of art we know as helmets. Now, you just need to decide which color is for you.
The D3 Helmet is constructed from technologically advanced aerospace carbon, and has been crafted following the Troy Lee Designs blueprint, ensuring safety and flaunting style. The D3 Helmet comes with 2 adjustable visors for custom height placement, and machined titanium screws for reduced weight. The D3 takes advantage of a dual density shock pad system that helps absorb smaller impacts, withstand multiple hits, and add more durability to the single impact absorbing EPS liner.
A removable, washable and replaceable comfort liner is constructed of CoolMax and Dri-Lex materials which efficiently wicks away moisture to keep you cool, comfortable, and odor-free. Taking breathability and airflow to the next level, the D3 Helmet features 14 intake ports over the forehead, brow, and chin areas to guide air past your head, while the 6 high-flow exhaust vents release hot air ensuring an even flow of cool air throughout the helmet's interior.
