Bright vs. Dark: Which Cycling Jersey Colors Keep You Coolest in Summer?

Summer cycling is a balancing act. You want to stay cool, protect your skin from the sun, and remain visible on the road, all while riding hard in the heat. One of the most debated questions among cyclists is surprisingly simple: should you wear bright or dark cycling jerseys in summer?
The answer isn’t as straightforward as “light is always cooler.” Let’s explore the science behind colour, heat, UV protection, and visibility to help you choose the smartest jersey colour for hot-weather rides.
The Science of Colour and Heat Absorption
At a basic level, colour affects how much heat fabric absorbs. Dark colours, like black or navy, absorb more sunlight, converting it into heat. Light colours, such as white, yellow, or pastel shades, reflect more sunlight, which generally helps keep the fabric cooler to the touch.
This is why you’ll often feel a black jersey heat up faster when standing still in direct sun. However, cycling isn’t a static activity, and airflow changes the equation significantly.
Why Dark Jerseys Aren’t Always Hotter
When you’re riding, airflow plays a huge role in cooling. Modern cycling jerseys are designed with advanced fabrics that wick sweat and allow heat to escape efficiently. In some cases, dark jerseys made from high-performance materials can cool just as effectively as lighter ones.
Dark colours can also help with moisture evaporation. By absorbing heat, they may speed up sweat evaporation when airflow is strong, which can actually enhance cooling during fast rides. This is why some professional cyclists still race in darker kits even in summer.
UV Protection: Light vs. Dark

One overlooked factor is UV protection. Darker colours generally provide better protection from ultraviolet rays because they absorb more UV radiation rather than allowing it to reach your skin. Light-coloured fabrics, especially thin or poorly constructed ones, may allow more UV penetration unless they’re specifically treated or tightly woven.
If you’re riding for long hours under intense sun, a darker jersey with a high UPF rating can offer better skin protection, even if it feels slightly warmer at first.
Fabric Matters More Than Colour
Colour alone doesn’t determine how cool you’ll feel. Fabric technology is often more important. Breathability, moisture-wicking ability, mesh panels, and fit all influence temperature regulation.
A well-designed dark jersey with ventilation zones can outperform a poorly made light jersey that traps heat and sweat. This is why experienced cyclists prioritise technical construction over colour trends when choosing summer kits.
Visibility and Safety on Summer Rides
Visibility is another critical factor, especially during early morning, evening, or high-traffic rides. Bright colours like neon yellow, orange, and light green stand out dramatically against roads and natural backgrounds, making you more noticeable to drivers.
Dark jerseys may look sleek, but they can blend into asphalt and shadows. Many cyclists compromise by choosing lighter or brighter colours for daytime riding or jerseys with reflective details that boost visibility without sacrificing style.
So, Which Colour Should You Choose?

If your rides are slower, longer, or involve lots of climbing and stops, lighter colours may help you feel cooler in direct sun. If you ride fast, generate strong airflow, and wear high-quality technical fabrics, darker jerseys can perform just as well, while offering superior UV protection.
For maximum comfort, the ideal solution is balance: choose colours you enjoy, ensure the fabric is lightweight and breathable, and consider visibility features for safety. Ultimately, the “coolest” jersey is the one that works with your riding style, climate, and performance needs.
Ride Smart, Not Just Light
Summer cycling comfort isn’t dictated by colour alone. Smart fabric choices, proper hydration, and sun protection matter just as much. Whether you prefer bold brights or classic dark tones, choosing a well-engineered jersey from Scody can make all the difference on hot rides, helping you ride cooler, longer, and stronger in premium performance gear.
