SUMMITS, SLOPES AND POWDER DAYS. The new Tenet™ is designed for all-mountain activities. Its hybrid construction combines the low weight of the In-Mold lower part with the robustness of the hard shell upper. The result is comfort and mobility for several long seasons on the mountain. The Tenet is equipped with the advanced safety technology Mips®, which can reduce the rotational energy in certain impacts through Giro's unique two-piece construction. To adapt to changes in the weather, Giro has integrated adjustable Thermostat Control, which allows you to regulate your temperature yourself. Equipped with the In Form 2 Fit System and Giro's breathable Ionic+® padding, the Tenet offers an excellent fit and plenty of comfort. Giro - Tenet\u2122 Mips\u00ae 23/24 Ski Helmet matte trail green
