evo.com | Giro Ski and Snowboard Helmets > Inspired by high-end auto aerodynamics, the Giro Jackson MIPS Helmet brings that same airflow intelligence to the mountain. The new Passive Aggressive Venting system manages temperature whether you're ripping, touring, or just standing around. No more overheating on bootpacks or freezing on chairlifts. Ultra-lightweight construction teams up with MIPS technology and the dialed In Form 2 Fit system, while that subtle brimmed profile and clean lines play perfectly with Giro goggles for a setup that looks as good as it performs. In-Mold Construction In-Mold Construction fuses a tough polycarbonate outer shell with the helmet's impact-absorbing foam liner. The fusion process allows for better ventilation systems, making in-mold helmets lighter and cooler than traditional helmets. Passive Aggressive Venting System Clean linear exterior vents combine with ergonomic interior channeling create optimal airflow and temperature regulation. This auto-venting technology manages airflow and temperature regardless of activity level. In Form(TM) 2 Fit System The In Form 2 Fit System is lighter and lower profile than the original, making it even easier to dial in a custom fit in seconds - even with gloves on. An improved dial design provides up to 6 cm of adjustment plus enhanced stability. Polartec(R) Power Grid(TM) Padding CE EN1077 | Giro Jackson MIPS Helmet 2026 - Medium in Gray
