Active Bottle Cooler™
The Active Bottle Cooler™ by Rubytec® is an inventive product that allows you to keep beverages cool and fresh when the weather’s warm. This lightweight bottle cover doesn’t only insulate, it also cools beverages ACTIVELY through an ancient physical principle. Ever since Antiquity, drinking water was kept in earthen jugs or leather sacks. Small amounts of vapour were able to escape through the pores of the containers, which kept the contents of the jug or sack cool.
The Rubytec® Active Bottle Cooler is composed of two layers: an inner and an outer cover. The inner cover is made of intelligent, multilayer, breathing and water repellent material. The inner cover, which gets wet, is made of woven cotton that has been treated with an anti-mould and antibacterial agent. Depending on the air humidity degree, the Active Bottle Cooler can cool its contents well up to 6 to 13 °C below the ambient temperature!
