When choosing running clothing for your next workout, It’s important to consider comfort, breathability, and fit. Consider what types of clothing you usually feel comfortable in, and also the weather conditions you expect during your typical runs. For example, if you run inside on a treadmill you might want to avoid baggy or loose-fitting clothing, and if you run outside in a hot climate you might want to choose something with more breathability like clothing with ASICS ACTIBREEZE Technology.
