Visma’s Black Tour de France Jersey Designed to Stay Cool, Not Overheat

Visma-Lease a Bike stated on July 2, 2026, that its black Tour de France jerseys will not cause riders, including Jonas Vingegaard, to overheat. According to reporting from Canadian Cycling Magazine, the team claims advanced fabric technology offsets the thermal absorption typically associated with dark colors to maintain rider core temperatures during high-heat stages.

The announcement addresses concerns regarding the physics of heat absorption, as black fabrics typically absorb more solar radiation than lighter colors. Visma-Lease a Bike asserts that the specific textile engineering used in the current kit prevents this absorption from negatively impacting athlete performance.

How does the jersey prevent overheating?

The team attributes the jersey’s thermal regulation to the technical properties of the fabric. While the specific material composition was not detailed in the report, Visma-Lease a Bike maintains that the garment’s breathability and moisture-management capabilities counteract the heat trapped by the black pigment.

High-performance cycling apparel typically utilizes synthetic blends designed to move sweat away from the skin and increase airflow. In this case, the team claims these features are sufficient to ensure that Jonas Vingegaard and his teammates do not experience a temperature increase compared to wearing lighter-colored kits.

Why does jersey color matter in the Tour de France?

Thermal regulation is a critical factor in endurance sports where riders face prolonged exposure to direct sunlight. Increased core body temperature can lead to premature fatigue, decreased cognitive function, and a higher risk of heatstroke.

According to Canadian Cycling Magazine, the debate over the black jersey stems from the known tendency of dark surfaces to absorb a broader spectrum of light energy, which is then converted into heat. This is particularly relevant during the Tour de France, where riders often compete in temperatures exceeding 30 degrees Celsius.

How does this compare to standard cycling gear?

Most professional cycling teams prioritize aerodynamic efficiency and moisture wicking over color-based thermal management. However, the use of a predominantly black kit is a distinct choice that invites scrutiny regarding heat load.

The claim by Visma-Lease a Bike suggests a shift toward relying on textile science—such as specialized weaves or heat-reflective treatments—to negate the traditional disadvantages of dark clothing. This contrasts with traditional approaches that favor white or neon colors in extreme heat to reflect solar radiation.

The performance of Jonas Vingegaard, a primary contender in the race, makes the technical specifications of the kit a point of interest for analysts monitoring the team’s marginal gains strategy.
