MIPS Ski Helmet Kelvin II - Lightweight Protection for All

In this review of the Kelvin II MIPS ski helmet, the bottom line is simple: it is a versatile, safety-focused helmet best suited for recreational skiers, snowboarders and youth who want modern impact protection without a heavy or bulky feel. The helmet's defining strength is its inclusion of MIPS alongside a reinforced ABS shell and an EPS core, which together prioritize rotational and linear impact management while remaining comfortable for multi-day use. Fit, ventilation and warmth are balanced so the helmet works equally well for on-piste runs, lift rides and park laps.

Key Features

• MIPS protection: The Multi-direction Impact Protection System adds a low-friction layer to reduce rotational forces in oblique impacts for increased head safety.
• Reinforced shell and EPS core: A durable ABS shell paired with a shock-absorbing EPS inner reduces impact energy transfer while keeping the helmet structurally sound.
• Adjustable fit system: The rear dial and removable lining let users fine tune the fit to relieve pressure and keep the helmet secure on varied head shapes.
• Ventilation design: Fourteen air vents promote airflow to help regulate temperature and shield the wearer from freezing winds on cold days.
• Modular warmth: Detachable earmuffs and a soft chin band provide cozy insulation when needed and can be removed for milder conditions.
• Lightweight construction: In-mold build reduces overall weight so the helmet feels less fatiguing during long sessions.

Who It's For

The Kelvin II is ideal for recreational skiers and snowboarders - teens and adults - who prioritize a modern protective system and a comfortable, adjustable fit. Riders who switch between resort laps and park tricks will appreciate the balance of protection, ventilation and detachable warm components.

Hardcore racers or backcountry skiers who require highly specialized ventilation control, extreme temperature management, or certifications beyond the standard shell and EPS construction may want to compare models tailored specifically for racing or avalanche use.
