What to Wear Under an F1 Racing Suit: Base Layers & Moisture Control

When driving in high-heat environments or professional motorsport events, what you wear underneath your race suit is just as critical as the suit itself. Heat exhaustion and sweat buildup inside the cockpit reduce focus, while improper synthetic materials under a race suit can pose severe burn hazards in an emergency.

1. Why Proper Base Layers Matter

A quality motorsport base layer acts as a second skin. It pulls perspiration away from your body through active moisture-wicking technology, keeping your skin dry and helping regulate body temperature under intense conditions.

• Moisture Control: Wicks away sweat to prevent body overheating and cockpit fatigue.
• Thermal Protection: Flame-resistant Nomex® or aramidic blends slow down heat transfer.
• Suit Protection: Protects your outer suit lining from body oils and salt degradation.

2. What Materials to Avoid Under a Racing Suit

Never wear standard synthetic fabrics like polyester, nylon, or spandex directly under a racing suit without fire-retardant certification. In high-heat situations, non-treated synthetics can melt onto skin and cause critical injuries.

Stick exclusively to certified fire-retardant undershirts, pants, and balaclavas made from Nomex® or specialized moisture-wicking cotton linings designed for race applications.
