Thermos flask made of double-walled stainless steel
The Gemstone Thermos bottle from Sigg is as high quality and robust as real gemstones. The name of the Gemstone series is program and the thermos flasks are indispensable on the way. Made of double-walled stainless steel, the bottle insulates hot tea and coffee perfectly and even cold drinks stay cold for a long time. It is ideal for travelling and is also a practical companion for sporting activities such as hiking, mountain biking and canoeing.
The Gemstone thermos flask is available in different sizes and colours.
