This stainless steel thermos features a double-wall vacuum insulation to keep cold beverages cold and hot beverages hot. The multistripes of green, red, yellow and indigo were introduced on the Hudson's Bay Point Blanket at the end of the 18th century. The colours were chosen because they were popular, and easily produced using good colourfast dyes. These four colours are also sometimes known as Queen Anne's colours, since they first became popular during her reign (1702 - 1714). Today, you'll find an assortment of clothing, accessories and home items adorned with the HBC stripes.
