Bend and stretch in total confidence in this sleek, long-sleeve layer. Still lightweight, it's crafted from our updated InfinaSoft fabric, which is now ultrasoft with stretch designed to recover its shape wear after wear. Nike Dri-FIT technology moves sweat away from your skin for quicker evaporation, helping you stay dry and comfortable. Thumbholes let you extend your coverage and help hold the sleeves in place while you move. Princess seams make for smooth, tailored fit.
