The Smith Summit Mips is a backcountry ski touring helmet that meets alpine ski standards and the EN 12492 mountaineering standard. It has Mips, Zonal KOROYD, a BOA dial fit, and 33 vents. This one is Matte Black in size Large.

What it's for

Ski touring and ski mountaineering, where one helmet has to cover the skin track, the boot pack, and the descent. The mountaineering certification covers hazards like falling rock and ice, and the ski certification covers the ride down.

How it works

Dual certification: EN 12492 is the standard for mountaineering helmets. ASTM F 2040 and EN 1077 Class B are snow sport standards. A helmet that passes both is tested for each use.

Hybrid shell: A durable outer shell in high wear areas combined with a light in mold shell elsewhere.

Zonal KOROYD: Panels of welded tubes in key zones crush to absorb impact energy and let air pass through.

Mips Brain Protection System: A low friction layer that reduces rotational forces from angled impacts.

BOA 360 Fit System: A dial tightens a band around the whole head in small steps.
