The Smith Altus MIPS Snow Helmet combines ultra-light, in-mold construction with the increased protection of Koroyd and MIPS. The Altus ensures a dialed-in fit thanks to the tried-and-true VaporFit adjustable fit system. This modern, low-profle helmet design also includes a slimline venting system with a low-profile and intuitive shutter button to adjust airflow even with a gloved hand, allowing you to cool off or stay warm. The search ends with the new feature-packed Altus.
