TLD has gone and done it again and added another stylish and feature-packed helmet to their MTB full-face line-up with the D4 Composite MIPS Helmet. With a roster stacked with some of the best riders on the planet, you can be sure that the D4 has been thoroughly put through its paces to provide you with one of the most refined full-face helmets ever created. Who's this item for: Riders that demand the best and will not compromise when it comes to protecting their head. This is a helmet designed for people that like going stupidly big, and stupidly fast....and looking cool in the process. Construction: Lightweight aerospace fibreglass shell. In-mould polycarbonate around exposed EPS and vent openings to increase strength and durability. Rotational liner: All D4 helmets feature a MIPS liner to protect against rotational forces to the brain from certain impacts. Straps: Chinstrap uses lightweight metal D-rings and hardware. Retention System: There is no dial-type retention system with this helmet. The fit is adjusted via the thickness of the cheek pads. Ventilation: High-flow ventilation system channels fresh air through the headliner to force hot air out through the exhaust ports. Padding: The cheek pads and liner feature XT2 and X-Static technology to keep things fresh in there. The Australian Standard version of the D4 Helmet is available in 3 shell sizes only, but an additional/alternate sized headliner and cheek pads are included in the helmet box to fine-tune the fit to your head. XS/S helmet comes with a SMALL set of padding installed and with a complete set of X-SMALL liner and cheek pads. M/L helmet comes with LARGE padding installed and a complete set of MEDIUM liner and cheek pads. XL/XXL helmet comes with XL padding installed and a complete set of XX-LARGE liner and cheek pads. Visor: The visor is adjustable with metal hardware. Weight: Approx 1050 grams depending on size.
