The Brooks Women's Dash Cooling 4" Short is ultra-lightweight and breathable, making it a great choice for hot-weather runs. Strategic ventilation along the sides and back promotes airflow to help keep you cool as the miles add up. A wide waistband provides a secure, stay-put fit, while the zippered rear pocket keeps your phone, gels, or other small essentials close at hand. Sweat-wicking fabric helps you stay cool and comfortable, so you can focus on your training.
