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. Since all this protection is useless if you don’t want to wear it, we dialed up the comfort level with a micro-adjustable BOA® 360 Fit System that adapts to your whole head. A sweat-wicking, odor-fighting liner keeps you warm, while a front and rear adjustable 24-vent design lets you regulate airflow as needed.
