Riding in the Heat

Lightweight Jersey Guide

When the heat ramps up, every gram, every breath of airflow, and every drop of sweat matters. Lightweight Jerseys are designed to help you stay cooler, ride longer and perform stronger. 

At first glance, lightweight jerseys might seem less performance-focused - there’s less fabric, less structure, lighter finishing touches. But the reality is the opposite. Finding the perfect fabric that’s feather-light yet durable, breathable yet supportive, and ensuring a fit that works in dynamic riding positions, these are all carefully considered. Nothing is sacrificed. in fact, every detail is more intentional.

When temperatures rise, your body works overtime to keep itself cool. The wrong jersey can trap heat, cling with moisture, and make every pedal stroke feel heavier. But a well-chosen lightweight jersey actively works with your body, wicking sweat, increasing airflow, and reducing distractions. Whether you’re attacking humid climbs or cruising in the summer sun, it’s one of the most important pieces in your summer kit.

The importance of pairing a summer base layer

Wearing a base layer in summer might sound counterintuitive. Why add more when you’re already trying to stay cool?

The answer is simple: the right base layer actually helps you stay cooler. A lightweight, technical base layer sits close to the skin and rapidly wicks sweat away before it can saturate your jersey or slow down evaporation. That moisture is then pulled to the outer layers, where it can evaporate more effectively, keeping your core temperature more stable and your skin drier.

A good summer base layer such as the Pro Air Base Layer or Pro Mesh Base Layer works hand in hand with your jersey to regulate body temperature, prevent overheating, and minimise chafing. For riders pushing hard in hot conditions, it’s a smart, often-overlooked upgrade.
