Great things come from the "Green State" known as Vermont...Maple syrup, cheese, and our famous copper screw-top drinking vessel known as The Vermonter Flask! Similar in size and shape to our best-selling Great American Flask, this unique flask features one major difference: A machined screw-top that guarantees a 100% leak proof flask wherever and whenever you use it. This unique flask has been specially designed to accommodate the needs of those who use and rely on their flasks on a regular basis. For a taste of history, straight from America, it would be hard to find a more fitting flask. Twist, sip, enjoy.
