When you're on your DH mountain bike and squeezing out every last ounce of speed things can go very wrong very quickly. A misjudged line. A high-speed washout. A clipped handlebar. Perhaps too much speed into a big booter. It's during those living on the edge moments you'll be glad of the protection of the MTB Gravity 4.0 Helmet.
Impact Protection Performance
The Gravity 4.0 boosts confidence thanks to its host of protective features. The heart of the 4.0 is a dual foam construction, featuring EPS + EP0 impact foams. In combination, these two foams work hard to soak up the forces of both slow and high-speed crashes. The foam inner is covered by a tough Polymer shell, enhancing structural strength and durability. And for particularly gnarly trails, the 4.0 is fully neck brace compatible.
The visor not only keeps off sun and dirt but in the event of a crash, it's also designed to break away, reducing the effects of rotation force impacts. You also have a removable mouthpiece ventilation cover - leave it on when you want extra protection, pop it out when ventilation is more important.
360 ̊ Turbine Technology
The Gravity 4.0 also features Leatt's 360 ̊ Turbine Technology. This tech is focused on reducing the damaging effects of a crash on your brain. It works via 360 ̊moving discs, all made from an energy-absorbing material. These impart a reduction of rotational acceleration to the head and brain by up to 40%. The system also improves the absorption of impact energy - it reduces peak brain acceleration by up to 30% at the impact speeds associated with concussion.
Ready for DH Action
When you're getting rowdy, you're sure to feel the heat build. But that's not a problem. The Gravity 4.0 has a total of 22 air vents, creating a rush of cool air to the head when you're up to speed. This keeps fresh air circulating and allows warm sweaty air to escape.
Talking of sweat, the Dri-Lex® liner is quick to wick moisture off your skin, leaving you feeling drier and more comfortable. The anti-odour treatment also prevents nasty niffs, ensuring you're not causing a stink on the uplift. And to keep that always fresh feel, it's easy to remove and wash.
Lastly, with its Fidlock magnetic closure system, it's super quick and easy to pull on and remove your helmet. Less fuss. More riding.
