The Sowden thermos bottle 0.35 litres from the Danish brand HAY is a flexible thermos with lid in bright and cheery colours. Designer George Sowden has created a playful expression full of vibrant hues that contrast against one another to create a dynamic yet thoroughly practical thermos. Crafted from dual layers of stainless steel, the bottle is suitable for enjoying both hot and cold beverages. The bottle also features a plastic cap that screws onto the top.
