The women's Seasonless Short Sleeve is an instant favorite and added updates that help you get the most out of every season. From sunshine, to foliage to winter frost, this running wardrobe mainstay is made with new lighter weight, exceptionally soft fabric that helps you enjoy the scenery in comfort any time of year. Plus, baby merrow seaming helps reduce chafing while you move. The women's Seasonless Short Sleeve features an athletic fit cut from soft, stretchy NB dry fabric that wicks moisture away when your run heats up. A shaped hem and rib knit collar help tailor the fit, while reflective hits on the front and back offer a bit of day-and-night shine.
