When you spend more days on the mountain than off, the Smith Nexus MIPS adult winter sports helmet 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. Add MIPS® (Multi-Directional Impact Protection System) for increased safety and you have an advanced helmet design. Since all this protection is useless if you do not want to wear it, the comfort level was dialled up with a micro-adjustable BOA® 360 Fit System that adapts to your whole head. The sweat-wicking, odour-fighting liner of this alpine ski or snowboard helmet will keep you warm, while a front and rear adjustable 24-vent design will let you regulate airflow as needed.
