SMITH Trace MIPS Cycling Helmet - Lightweight Ventilated Protection

In this review of the SMITH Trace MIPS helmet, the bottom line is simple: this is an excellent choice for riders who want a lightweight, well-ventilated helmet with high-end impact protection and seamless eyewear integration. The Trace MIPS stands out primarily for its combination of MIPS Protection System to reduce rotational forces and extensive zonal Koroyd coverage for energy-absorbing, ventilated impact protection, making it a strong pick for commuters and recreational cyclists who prioritize safety without sacrificing comfort.

Key Features

• Zonal Koroyd coverage: Provides lightweight, energy-absorbing channels that crush progressively on impact while maintaining consistent ventilation across the shell.
• MIPS Protection System: Reduces rotational forces from angled impacts to help protect the brain during crashes.
• Integrated skeletal structure: Creates a roll cage that adds strength to the helmet and helps distribute impact forces for added protection.
• VaporFit dial adjustment: Offers 270-degree fit adjustment with a single turn of the dial so riders can quickly refine fit on the trail or road.
• AirEvac ventilation: Works with Smith goggles and eyewear to keep lenses fog-free and manage airflow for all-day comfort.
• Ionic+ lining and low-bulk webbing: Sweat-activated odor control and lightweight straps improve comfort on longer rides.

Who It's For

The Trace MIPS is aimed at adult cyclists who want a premium-feeling helmet that balances protection, ventilation and eyewear compatibility; it suits commuters, urban riders and mixed-surface weekend cyclists who value a clean aesthetic and functionality. Riders who frequently use Smith performance eyewear will especially appreciate the AirEvac system and the helmet's eyewear integration.

Those who need a highly aero racing helmet or a full-face trail helmet should look elsewhere, since the Trace is designed as a versatile sport helmet rather than a specialized time-trial or downhill model. Also, riders seeking the absolute lightest race-specific shell may prefer ultralight race helmets with different construction priorities.

Pros & Cons

Pros

• Excellent protection package with MIPS and Koroyd for both rotational and linear energy management.
• Very good ventilation from 18 fixed vents, including a front horizontal vent that customers report keeps heads cool.
• Comfortable, adjustable fit from the VaporFit dial and low-bulk straps that reduce wind noise.
• Thoughtful integration with Smith eyewear and a design that supports a light mount and fog-free lenses via AirEvac.

Cons

• Not a specialized aero or full-face helmet, so performance-focused racers or downhill riders may prefer other models.
• At about 10 oz / 280 g (size M, MIPS), it is not the absolute lightest option for competitive racers seeking minimal weight.
