The Sub Zero 2.0 Cooling Towel by ProActive Sports stays soft even when dry. The active cooling technology immediately cools up to 15 degrees below the outdoor temperature. Simply wet and wring the towel out and it is ready for use. Sub Zero 2.0 provides a long-lasting cooling sensation and can be re-activated by simply wetting the towel again. The towel comes in a reusable carabiner clip storage tube, so you can transport your wet towel without getting everything else wet. Great for the gym, yoga, cycling, golf, basketball, workouts, jogging, hiking, gardening, tennis, or just chilling at the beach.
