Learn how to pick the best athletic shorts for hot-weather running, focusing on fabric, fit, and features that keep you cool and comfortable.

Quick Answer

For summer runs, prioritize athletic shorts made from moisture-wicking, breathable fabric with UPF protection and a secure elastic waistband.

Why Fabric Matters More in Summer

In hot weather, cotton traps sweat and becomes heavy, leading to chafing and discomfort. Look for fabrics like recycled polyester and spandex blends that offer four-way stretch, moisture-wicking, and fast-drying properties. These keep you dry and allow full range of motion.

Don't Forget Sun Protection

Even on short runs, your legs are exposed to UV rays. Choosing shorts with UPF50+ protection adds a layer of defense without needing extra sunscreen on every run. It's a simple feature that makes a big difference over a summer of training.

Steps to Choose the Right Athletic Shorts

Check the Fabric Blend: Look for a mix of polyester and spandex or elastane. These materials wick moisture, dry quickly, and provide stretch. Avoid 100% cotton for running. A common mistake is choosing cotton shorts for comfort, but they hold sweat and cause chafing.
Prioritize Breathability and Drying Speed: Select shorts labeled as moisture-wicking and fast-drying. Microfiber fabrics enhance airflow and evaporation, keeping your skin dry. If the tag doesn't mention moisture-wicking, the shorts will likely feel heavy and wet during a run.
Confirm UPF Protection: For summer runs, choose shorts with UPF50+ to block harmful UV rays. This is especially important for midday or long-distance runs. Skipping UPF means relying solely on sunscreen, which can wear off with sweat.
Evaluate the Waistband and Fit: An elastic waistband with a flat drawstring provides a secure, non-binding fit. Ensure the shorts allow full leg movement without riding up. A too-tight waistband restricts breathing; a loose one causes constant adjusting.
Consider Eco-Friendly Materials: If sustainability matters to you, look for recycled polyester content. It performs just as well as virgin polyester and reduces plastic waste. Eco-friendly shorts often have the same durability and performance, so you don't have to compromise.
