The Santeco Kotka is a double-wall vacuum-insulated flask for coffee, tea or cold drinks. Its body is food-grade 18/8 stainless steel with BPA-free parts, and the leak-resistant hinged lid has a hole for clipping on a carabiner. The wide mouth makes filling and cleaning easy, the outside stays cool to the touch with hot drinks, and it will not sweat with cold drinks. This is the 500 ml size in Outdoor Khaki, a two-tone finish with a khaki top section over brushed stainless steel. It is a good size for a car cup holder, a desk or a day in the field. Hand wash only; do not put it in the dishwasher, microwave or freezer.
