The Troy Lee Designs A2 MIPS Helmet is breathable, comfortable, and one of the most-thoroughly designed helmets out there when it comes to safety. With dual-density foam, MIPS technology, and a break-away visor, it is designed to redistribute and neutralize impact from both fast and slow crashes. While comfortably padded, the helmet does not sacrifice on ventilation, with efficient vents and a lightweight feel. Common complaints are about the visor, which does not allow space for goggles, while also not sitting quite well enough to block out low sun.
