What Our Gearhead(R) Experts Are Saying:"This jacket became a quick favorite for transitional runs and unpredictable weather. It sheds light rain, packs down small, and the vented back really helps when I start to heat up mid-run. The Dri-FIT fabric keeps sweat from sticking around, and I love how the fit feels fast without being restrictive."When we're chasing miles or just chasing daylight, the Nike Swift Repel Packable Jacket keeps pace. Using real feedback from runners, Nike dialed in the fit and function-reducing chafing, boosting breathability, and adding a few smart touches like reflective details and a built-in whistle. Lightweight and streamlined, this jacket helps us adapt to changing conditions on the go. Dri-FIT technology pulls moisture away from our skin to keep us dry as the miles add up, and underarm-friendly sleeves help us move freely without rubbing. Mesh-lined vents release heat when we're pushing tempo, while zippered pockets secure the essentials. And when we no longer need the layer? It packs into itself for minimal bulk. Lightweight coverage, runner-approved.
