Smith Nexus MIPS Ski and Snowboard helmet in size Large (59-63 cm). The color is Matte Slate/Black. 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® throughou t 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.
