The J-GPR is designed to manage linear and rotational energy to the head during impacts through its S.D.C. system. The J-GPR is quickly setting a new level for rider protection on-road and within racing. Riders today need a helmet that provides pro level protection, the sequential density construction of this helmet uses specific materials of differing density to manage the force of impacts. In order to achieve the highest level of performance, various stages of aerodynamic tests are performed in the wind tunnel test lab in parallel with live testing situations. With mouth, top, eyebrow massive, and multiple air vents system, JUST1 J-GPR is designed to maximize airflow to your head. Tried and tested ventilation that allows for proper extraction of heat from the helmet, allowing for a cooler ride in even warm weather conditions. The helmet back spoiler is designed to follow perfectly the rider suit hump to maximize the aerodynamics during the races.
