The Smith Holt is a great helmet for skiers and snowboarders looking for a simple style that can protect you anywhere on the mountain. Smith's Bombshell, hard shell construction is resistant to dents and dings from lugging around your gear, as well as big crashes in the park. Bombshell is made with injection molded ABS material to be durable and protective. AirFlow Climate Control pumps air through the 14 vents located throughout the Holt to keep you cool if you start to get overheated on the mountain. The AirEvac Ventilation System keeps a flow of cool air moving across the top of your goggles and out though the back to prevent fogging. The Lifestyle Fit System uses elastic that self-adjusts around your head for a comfortable fit. The Holt has the ability to be used the rest of the year for biking or skating too, so you only need a single brain bucket for any action sport you participate in.
