Cooling collar – neither water nor a refrigerator are required. This practical cooling bandana is ideal for summer – it cools quickly and all by itself due to its gel filling. The gel filling is non-toxic and comfortably soft. If the cooling effect decreases, the cooling bandana only needs to be put at a cold place like a shadow or a tiled floor – it recovers after a short time and then cools again. The colder the place, the quicker the collar is able to cool again. It cools to a comfortable temperature which is 3-4? lower than the body temperature. It is immediately ready for use and can be used as often as required.
