Forefront 2 MTB Helmet for Adults - Lightweight MIPS Protection

In this review of the Forefront 2 MTB Helmet for adults, the bottom line is simple: this helmet is best for riders who want a lightweight, well-ventilated option that prioritizes modern impact protection. The review finds it particularly suited to trail and enduro riders who wear goggles or performance eyewear, because the design integrates Smith optics compatibility and an AirEvac ventilation system that helps keep lenses fog-free. Fit and adjustability are strong points thanks to the VaporFit dial, and the inclusion of MIPS plus a Koroyd energy-absorbing core sets it apart for safety-conscious cyclists.

Key Features

• Koroyd coverage: Provides lightweight, energy-absorbing and ventilated impact protection across the helmet to reduce blunt-force transfer.
• MIPS Brain Protection System: Reduces rotational forces in angled impacts for improved head protection in real-world crashes.
• VaporFit dial: Delivers 270-degree micro-adjustability so riders can dial in a secure, comfortable fit quickly on the trail.
• AirEvac ventilation: Works with Smith goggles and eyewear to channel airflow and help prevent lens fogging during sustained efforts.
• Integrated roll cage: The skeletal structure adds reinforcement and impact strength without significant extra weight.
• Adjustable visor and storage: A three-position visor and front/rear eyewear channels keep goggles stored and positioned for varied light conditions.

Who It's For

The Forefront 2 is aimed at adult mountain bikers who ride trails, enduro stages, or all-mountain terrain and value a balance of protection, ventilation, and eyewear integration. Riders who regularly use goggles or Smith performance eyewear will benefit from the AirEvac system and the built-in storage channels.

Less appropriate for pure road racers or riders who prefer very minimal helmets without a visor; also those seeking the absolute lightest race-specific road lid should look elsewhere. This helmet is a better match for off-road use where the visor, coverage and MIPS protection deliver practical benefits.

Pros & Cons

Pros

• Comprehensive protection with Koroyd and MIPS for both energy absorption and reduction of rotational forces.
• Comfortable, easily adjustable fit using the VaporFit dial for secure 270-degree adjustment.
• Excellent ventilation with 20 fixed vents and AirEvac integration to keep airflow steady and reduce fogging.
• Thoughtful eyewear compatibility and storage make transitions between goggles and glasses simple.

Cons

• At 14oz / 380g (size M, MIPS) it is lightweight but not the absolute lightest option for aggressive climbers prioritizing every gram.
• The three-position visor has limited adjustment compared with some specialty models, though it covers most use cases.
