Hybrid construction meets all-mountain demands in the Giro Tenet MIPS Helmet. This clever design fuses in-molded lightness below with hard-shell durability up top, creating a lid that’ll handle multiple seasons without weighing you down or falling apart after a few chair lift dings. MIPS technology reduces rotational energy during impacts, while Thermostat Control venting and breathable Ionic+ fleece let you fine-tune comfort.
