Our cooling scarf is fantastic. Prior to cooling with ice or refrigeration, our neckwear will always be 20°F/5°C cooler than the surrounding air. They are easy to use and to clean. With each individual neck cooler cooling scarf instructions for activation are printed on them. If you are looking for advice or time-saving tips, check out the links on this and other websites. All our neck coolers are domestically produced. Watch out for imitations that break, fall apart, and fail to cool correctly; these should be avoided. Our product is the original so if you are not getting it from us, you might have a knockoff and you will get insufficient cooling and uses from it.
