What to Wear Cycling in 25°C
At 25°C and above, the challenge shifts from staying warm to managing heat. Aerodynamic, ventilated kit minimises fabric contact and maximises airflow. Hydration becomes the dominant performance variable — sweat rates at 25°C can exceed 1 litre per hour on hard efforts.

FAQ
What to wear cycling in 25°C?
Aero or short-sleeve jersey, bib shorts, short-finger gloves, thin summer socks, and sunglasses. At 25°C, prioritise ventilation above everything else.
Do I need a base layer at 25°C?
An ultralight mesh base layer can help by wicking sweat away from skin faster, keeping you cooler overall. Avoid anything with thermal properties.
