Leatt DBX 5.0 Full Face Enduro Helmet XL 61-62cm Black, Blue & White (RRP: £280

Aesthetics are always a subjective metric, but there's no denying that no one thinks a huge helmet looks cool. Thus, the lower-profile—both in graphics and in bulk—DBX 5.0 adds style along with safety, as there is less helmet to grab the ground when you crash, which follows the latest research citing rotational forces as a prime factor in head injury. A visor designed to break away on impact further reduces the chances of the helmet catching rather than sliding.
Take a look inside the DBX 5.0's shell, and you'll find some interesting structures. Called "Turbines," the little blue posts are made from ArmourGel, which is usually soft for comfort, but stiffens up on impact. However, thanks to the substance's composition and the Turbine design, they still move enough to reduce 40% of rotational acceleration to the head and brain. This helps cut down up to 30% of concussion level head impact.
