The Smith Session helmet is designed for all-mountain riders who require low weight and ventilation for the climbs but the safety of high quality impact protection for downhill sections.

The Session uses zones of Koroyd® Impact Protection, a technology made from welded cylinders laid on end. This forms a crumple zone, the cylinders absorbing the impact and collapsing evenly. This technology provides lots of impact protection for a less weight and bulk but allows greater ventilation.

Large holes on the top channel air through the Koroyd® zones to keep you cool and an antimicrobial liner keeps odours at bay. The adjustable visor has three settings to accomodate your glasses or goggles.

The Session uses Smith's VaporFit™ adjustment system, tightening with a simple dial. It can also be moved in four different directions for a secure, personalised fit.

The Session also features the MIPS® Brain Protection System for extra safety. This additional layer between the padding and foam reduces the impact of angled falls by protecting against rotational movement in the brain.
