When it comes to helmets there used to be only two choices. We could choose the all-out full face moto type or go with something of the swiss cheese roadie persuasion. Thank goodness folks like Troy Lee Designs stepped in and started meeting us in the middle with helmet styles like the A1. These are full coverage helmets that suit the needs of a more modern trail and all-mountain rider. They continue to perfect the fit and style of this light weight lid which features a polycarbonate shell, extra coverage at the temples and lower cranium area, tons of ventilation, a 1 piece Coolmax comfort liner, and customizable fit with a three-position stabilizer basket.
Troy Lee Designs A1 MIPS helmet is equipped with the patented MIPS system to reduce the rotational forces to the brain in the case of an oblique impact. Where most helmets are tested for vertical impacts, studies have shown that the human brain is more sensitive to oblique impacts. MIPS technology mimics nature's own method of reducing forces transferred to the brain in the event of a crash. When subjected to an oblique impact, a membrane between the brain the skull allows the brain to slide along the inner surface of the skull, which ultimately reduces the forces transferred to the brain. MIPS helmets use a low friction layer between the shell and liner to mimic this process, which significantly reducing the forces transferred to the brain.
