Quick drying Microfiber cooling towel in black 210D Polyester Mesh drawstring pouch. Microfiber towel made of 10% Nylon/90% Polyester (200 GSM). Towel dries significantly faster than traditional terry cloth towels and can hold more than its own weight in water. When wet, towel cools for up to 2 hours; when dry, it absorbs sweat. To activate cooling function: 1 - soak towel, 2 - ring out excess water, 3 - snap to activate (to reactivate, re-soak, re-ring and re-snap). Great for everything from a workout to cleaning around the home. Microfiber is soft to the touch and gentle on skin. Hand-wash only.
