This isn't your standard running jacket. Harnessing seam-sealed DryVent™ technology, you'll get waterproof, windproof protection on cool morning sessions and sweaty midday runs. But you won't overheat or become too hot and clammy. Thanks to the breathable ripstop fabric, you'll stay cool and dry while you work up a sweat. We've added reflected logos to the sleeves, chest, back-right shoulder and lower back to help you be seen, day or night.
