Stainless steel double wall construction with vacuum insulation technology and a threaded steel lid. Modern technology allows us to create beverage holders with almost unbelievable thermal retention capabilities. The Therma-Pop will keep drinks cold up to 24 hours and coffee or cocoa hot or warm up to 12 hours. The contemporary design was inspired by the classic soda pop bottle and the special exterior powder-coat matte finish provides a firm grip with no sweating.
