The Ronhill Trail Tempest Waterproof Running Jacket is a super-lightweight waterproof jacket that is comfortable and durable. The jacket is manufactured with Aqualite, a fabric that provides all the benefits of a waterproof garment combined with complete wind protection. This provides a weather barrier and ensures optimal comfort in the worst weather conditions. The back vent of the jacket works with the breathability of the fabric, providing extra airflow and ventilation for extra comfort during intense training or warmer conditions. An adjustable hood, chin guard, and lock down full-length waterproof zip provide further element protection, keeping you warm and dry. A Pack-It system allows the jacket to be packed away into its own zip pocket, so that you can transport it easily.
