Using the same material as our Eskimo Throw Cooling Towel the Eskimo Cooling Collar is made to easily fit to your calf’s neck with quick secure Velcro straps. Simply wet down towel, place around animals’ neck and leave under the fan. The fans air flow will instantly activate the cooling properties of the collar. When the collar is dry simply take a pump-up sprayer with water and re soak the collar to reactivate the chilling capabilities. This collar can be left on all day and only takes a little water to be reactivated. Also, unlike other cooling collars the light weight fabric won’t weigh down the animal or create any extra body heat when it is no longer cooling.
