Series 40 Helmet SA2025 Flat Black Medium

The Series 40 Helmet SA2025 Flat Black Medium from ALLSTAR PERFORMANCE is purpose-built for motorsports competitors and safety-conscious drivers who demand certified head protection. Engineered to meet Snell SA2025 standards, this medium-sized helmet delivers impact absorption and structural integrity required for high-speed racing environments, autocross events, and amateur motorsports applications. The flat black finish provides a professional appearance while the integrated head and neck support system enhances stability during acceleration, braking, and cornering forces.

This helmet's design incorporates Snell SA2025 certification, an industry-recognized standard that validates rigorous testing for impact resistance, shell durability, and retention system reliability. The head and neck support architecture is engineered to manage rotational forces and distribute impact energy across the shell and interior padding, reducing peak g-forces transmitted to the wearer during collisions. At 5.04 pounds, the Series 40 balances protective mass with wearability for extended racing sessions, while the compact dimensions (11.75" × 11.05" × 14.8") ensure optimal fit and comfort within tight cockpit spaces common to race cars and high-performance vehicles.

Drivers competing in sanctioned motorsports events, amateur racing leagues, and track days benefit most from the SA2025 certification and head support technology built into this design. The medium size suits individuals with average head proportions and provides the snug fit necessary for safety harness compatibility and consistent helmet positioning during dynamic driving. Installation is straightforward—simply position the helmet over the head and secure the retention system; no additional mounting or modification is required. Verify proper fit before track use to ensure the helmet moves minimally when side pressure is applied and the retention system sits comfortably under the chin without restricting breathing or visibility.
