When running in warm weather, the right clothing will help you stay cool and comfortable.
In warm weather conditions, you’ll need less clothing – maybe a vest or crop top instead of a T-shirt. Remember to apply sunscreen of at least factor 15 on all exposed areas of your skin.
The type of fabric your clothing is made from also affect your comfort.
Cotton has the advantage of being cheap and is quick to soak up sweat as you run, but it retains this moisture, which makes it heavy and wet during exercise. What is more, cotton T-shirts usually have rough, uneven stitching, which can cause chafing and, in extreme cases, even bleeding. If you are going to wear cotton, it’s probably best to choose lightweight cotton because a dense weave, heavyweight material will feel heavy more quickly. Lightweight cotton will also chafe less than heavier fabric.
Wicking fabrics are an alternative to cotton. These are man-made fabrics designed to draw sweat away from the skin to the outer surface so that it can evaporate. This means that clothes stay light and feel dry.
Companies that specialise in running clothing may also include other design features for the comfort of the runner, such as mesh inserts for ventilation. ‘Technical’ clothes are likely to be more expensive, so it’s up to you to decide if the extra comfort is worth the price.
