The Altus Mips is an all-mountain helmet for riders who chase storm days as happily as bluebird groomers. The Regulator slider opens and closes the ten vents on the fly, so you can seal up in a Timberline whiteout and dump heat on the next sunny run. A light in-mold shell with zonal Koroyd and Mips handles protection, the VaporFit dial adjusts 270 degrees, and the removable ear pads are audio compatible.
