When you spend more days on the mountain than off, the Smith Nexus is your helmet for bomber protection that holds up season after season. In addition to a hybrid shell that balances a lightweight, low-profile design with a durable hardshell exterior, the Nexus steps up impact coverage with Koroyd throughout the helmet, a fully-vented material that absorbs more energy in a crash than traditional foam construction alone. Add MIPS for increased safety during angled impacts, and you have our most advanced helmet design. A sweat-wicking, odor-fighting liner keeps you warm, while a front and rear adjustable 24-vent design lets you regulate airflow as needed.
