Go light. Go Far. From skin track to boot pack and summit bids, the Smith Summit snow helmet is our lightweight go-to lid for backcountry touring and ski mountaineering. Its triple-certified design meets global alpine ski certs plus international mountaineering standards. The design blends a minimalist approach with mountaineering-specific details to keep it ultra-light yet ready for alpine pursuits. Zonal Koroyd and MIPS impact protection absorb energy in the event of a fall. A Smith custom BOA 360 Fit System offers a micro-adjustable fit that also collapses into the helmet for easy stuffing into your pack. External bungee loops offer secure attachment to the outside of a pack, too. Integrated headlamp strap routing keeps a light in place, and a beanie and ball cap-compatible design lets you match the weather conditions. Thirty-three fixed vents keep the air moving and your goggles or glasses fog-free. Go ahead and set your sights on the summit.
