The Smith Compass MIPS has a great look and extra protection for you to get out on the mountain. MIPS (Multi-Directional Impact Protection) uses a liner that can rotate inside the helmet upon impact to absorb some of the energy, rather than it getting transferred to your brain. The Adjustable Boa X Fit System has a dial on the back of the helmet that gets the fit perfectly snug on your head. Smith's X-Static Performance Lining is not itchy on your head, and wicks away moisture if you start to get sweaty. The AirEvac 2 Ventilation uses two vents located on the brim and channels that run through the helmet that keep air moving inside your goggles to prevent fogging, so you will always be able to see clearly on your way down the mountain. A Low-Profile Regulator Adjustable Climate Control regulates the 20 vents to keep you cool if you start to overheat, and warm should you get cold.
