Made for cross-country skiing, this comfortable adidas Terrex top will help you find your flow on the track and leave distractions behind. On the front, stretchy fabric ensures nothing limits your movement, and a hidden quarter zip offers on-demand ventilation. On the back, AEROREADY channels moisture away from your skin to help you maintain your focus. The slim fit means you can wear it under a jacket. Best of all, though, it's made using recycled materials so you can give something back to the great outdoors.
