Because you prefer to enjoy Prosecco, white wine and rosé well chilled, the Cold Bar cooling collar supports you in temperature management. The black cuff with cooling gel is ready to use after 6 hours in the freezer and then cools for up to 2 hours (depending on the ambient temperature). Particularly practical: With its Velcro fastener, the cooling sleeve adapts to the shape of the bottle in a simple design, and this also works with water bottles, for example. Tip: Ideal for picnics and all those moments when there is no fridge nearby.
