When clouds cover the mountain, zip into the Patagonia Women's Storm Racer Jacket and continue your trail running regimen. Its 2. 5 layer shell gives you reliable waterproof and breathable protection, and fully taped seams make sure raindrops don't seep through. Patagonia added a DWR coating to shed water for extra protection. The zippers at each upper arm allows plenty of ventilated airflow, and there are also slits at the back of the jacket for constant ventilation. Elastic wrists and adjustments at the hood and hem ensure a secure fit so you can run like it was just another day.
