A3 MIPS Helmet

• Product Details

  What Our Gearhead Experts Are Saying:

  "The Troy Lee A3 MIPS is the helmet I recommend for all-mountain riders who want more coverage than a standard trail lid without strapping on a full face. The extended temple and base protection is a meaningful upgrade over something like the A2, and the MIPS layer handles the angled impacts that cause the most problems in a real crash. Sixteen vents keep airflow moving on long climbs, and the breakaway visor is a detail I appreciate more than most it releases cleanly through a fall instead of torquing your neck. Great all-day helmet."

  All-mountain riding asks a helmet to cover a lot of ground technical descents, long climbs, the kind of unexpected moments that don't announce themselves before they happen. Troy Lee Designs' A3 MIPS is built for exactly that range, with extended coverage along the temples and base of the head that goes meaningfully further than a standard trail helmet without adding the weight and restriction of a full chin bar.

  The polycarbonate shell handles initial impact while the EPS foam layer underneath absorbs the force, and MIPS technology addresses the rotational forces that straight-impact ratings don't capture. Sixteen vents keep the helmet working for you on hot climbs, and positioned foam wicks sweat through long efforts. The rear stabilizer fit system dials in a secure, customized fit, and the three-position adjustable visor shields eyes from debris and glare while engineering a clean break away from the helmet through a crash to reduce impact forces. At 13.2 ounces it wears light enough to forget about until you need it.
