Light up the track or trail in the Icebreaker Women's Spark Short. The soft merino wool blend fabric regulates temperature to keep you cool when you're active, and it's blended with Lycra for unrestricted movement. A tight, short liner provides a supportive fit, and flatlock seams prevent chafing. The wide waist reduces pressure points and provides a flattering shape. It's finished off with a stash pocket to store your key or credit card and reflective tape on the side seams that helps you stay visible during evening runs.
