The Lucy Dashing Stripes Long-Sleeve Top is a uniquely-soft run layer thanks to specially-engineered Tactel fabric bringing a new level of softness along with the anti-tear properties of nylon. Wear the Dashing Stripes Long-Sleeve as a cozy next-to-skin baselayer, and then sport its contoured fit on race day for uninhibited strides. Flatlock seams will keep you from chafing whether you're jogging around town or training for your marathon.
