Leatt DBX 4.0 Mountain Bike Helmet

When ambition begins to outweigh talent, the Leatt DBX 4.0 MTB Helmet is the go to helmet for enduro and bike park riders. Packed full of Leatt's high-quality, no-nonsense tech and materials, the DBX 4.0 is THE option for riders that not only want to cover their noggins, but gain confidence in their riding as well. For creature comforts, the DBX 4.0 comes with a Dri-Lex moisture whicking, fully removable and washable liner and a magnetic removable mouth piece ventilation cover. With an ASTM DH certified fiber shell, the DBX 4.0 is lined with Leatt's energy absorbing 360 degree Turbine Technology which reduces rotational and concussion-inducing energy to the brain to bring you premium safety. The DBX 4.0 also comes equipped with a breakaway visor design to reduce rotation during a spill, and you can optimize your safety standards with the ability to pair this helmet with a neck brace if you wish (sold separately.)
