Columbia's CHILL RIVER SS W is a women's short-sleeve tee with a discreet back opening that combines femininity and technical features.
Made from a heat-adapted material of polyester and ethane fibers, this model is very comfortable to wear, as it features Omni-Wick technology that wicks away moisture to allow perspiration to escape, while Omni-Freeze technology enhances cooling to keep the athlete cool and dry even in the summer heat. Plus, the stretchy fabric allows for free movement.
And Omni-Shade UPF 50 protects the skin from UV rays.
