Smith - Persist MIPS

The Smith Persist MIPS Helmet is a lightweight, highly ventilated adult road cycling helmet tailored for daily training, weekend endurance rides, and gravel paths. It is a highly rated, mid-tier option in Smith’s lineup.

Key Technical Features

• MIPS Brain Protection System: Features a built-in low-friction slip liner designed to slide independently during an oblique crash, reducing dangerous rotational forces to the skull.
• Zonal Koroyd Coverage: Upgraded with honeycombed Koroyd inserts in key strategic impact zones to absorb more energy than traditional EPS foam while keeping the frame breathable.
• 21 Fixed Cooling Vents: Engineered with 21 internal airflow channels to consistently wick moisture and regulate temperature, even on steep climbs.
• AirEvac Ventilation System: Internal ventilation routing aligns with cycling eyewear, pulling hot air away from lenses to prevent fogging.
• Front Eyewear Storage: Pass-through channels molded into the front vents allow for secure docking of sunglasses when not in use.
• VaporFit Dial System: Equipped with a mechanical rotary dial for a customizable 270-degree fit adjustment, eliminating pressure points with one hand.
• Lightweight Frame: Minimizes neck fatigue over long rides, weighing approximately 300 grams (Size Medium).
