If 32 ounces is the gold standard water-bottle size, then the Iron Flask 32 oz Narrow Mouth Bottle With Spout Lid is the gold standard for water bottles. It’s made from the highest-quality stainless steel and features double-wall vacuum insulation for beverages that stay just the temperature you like (24 hours of icy cold drinks and 12 hours of piping hot drinks). The leak-proof spout lid and narrow mouth make it easy to sip, gulp, or store, and we also included a flip lid and a screw-on lid ‘cause we know how important it is to have extra options.
