Lightweight, downhill-certified, full-face helmet.

The Proframe RS Heatstack Helmet takes the lightweight breathability of the Proframe and elevates it to the next level of safety and performance. Featuring the all-new Mips® Integra Split protection system, which combines a dual-density foam - for high and low-speed impacts - and a Low Friction Layer between the two layers designed to reduce rotational forces in a crash that would otherwise be transmitted to the brain. The BOA® Fit System allows for a precise and adjustable fit in the pro-level, downhill-certified helmet.
