Heading into the backcountry is no joke, and neither are the performance features of the Envi Spherical helmet. But you don't have to go off the grid to reap all of its benefits. You'll notice its extremely lightweight construction allows you to make powdery turns and then tour back to the top without being weighed down. When you're feeling the burn and things start to heat up, easily control your temperature with the Thermostat Control and Stack Ventilation. The Envi also features Mips Spherical technology, which aids in the reduction of rotational energy during certain impacts for an additional level of confidence. Plus, you'll stay extra comfortable thanks to its Plush Max fleece that dries quickly and provides a super-soft feel.
