If you're new to cycling, you might be wondering: do you wear a shirt under a cycling jersey? While it might seem logical to add an extra layer, cycling clothing is designed to work a little differently. Let’s explore whether layering is necessary and when it might actually help.
Why Most Cyclists Skip the T-Shirt
The simple answer: you generally don’t need to wear a regular shirt under a cycling jersey. Cycling jerseys are made from technical fabrics designed to manage sweat, reduce friction, and keep you comfortable on the bike. Adding a cotton T-shirt underneath can trap moisture, cause chafing, and overheat your body during summer rides.
Instead, jerseys are meant to be worn close to the skin to wick moisture efficiently and allow proper airflow.
When an Undershirt Makes Sense
That said, there are times when wearing a technical baselayer under your jersey can actually improve comfort. On cooler days, a lightweight mesh or merino wool baselayer adds warmth and helps regulate body temperature. In hot conditions, a sweat-wicking summer baselayer can enhance ventilation and reduce sticking.
The key is using purpose-built cycling layers, not regular shirts.
