Simpson Racing Equipment Helmet Medium

The Simpson SD1 racing helmet (also called the SD1 SA2020 full-face auto racing helmet) is Simpson's lightest and most aerodynamic helmet. It is built for open-wheel dirt track racing. It is Snell SA2020 certified, and each helmet is hand built to order in New Braunfels, Texas.

Key Features:

• Snell SA2020 certification
• Lightweight, aerodynamic full-face design with a front chin spoiler for stability in open-cockpit cars
• No front ventilation, which helps keep dirt, dust and debris out. Top and rear vents provide airflow.
• Removable cheek pads and top pads in a range of thicknesses for a custom fit
• Removable gel earcups, with speaker cutouts for Simpson communication kits
• Moisture-wicking, washable modacrylic/aramid blend interior liner
• Double D-ring chin strap
• Compatible with head and neck restraints
• Anti-fog, anti-scratch visor as standard
• Aluminum tear-off posts included, compatible with Simpson tear-offs 10209C, 10209CP and 10209S
• Optional visors, including dark smoke, iridium, amber and chrome, and an optional rear spoiler for added stability

The SD1 combines a premium fit and low weight with the protection and track-ready features that dirt track racers look for. Simpson has built racing safety gear for decades.
