VACUUM INSULATION This double-walled insulated bottle will keep drinks cold for 24 hours, and hot for 12 hours. Your bottle also won't sweat (have condensation) if used for cold drinks due to the vacuum insulation. HIGH QUALITY STAINLESS STEEL This bottle has been built to last using high quality stainless steel, including all contact with liquids throughout the bottle and the lid. EASY CARRYING The faux leather strap ensures your lid won't go missing, and makes your bottle easier to carry. It is held securely to a steel ring around the neck of the bottle. ACCESSIBLE SPOUT The spout is extra wide, making it much easier to add ice cubes or a charcoal filter to the bottle. It also ensures easy cleaning. The steel rim has an inside thread for an optimum drinking experience.
