Camping. Hiking. Discrete sipping on the train — there are many circumstances when a flask comes in handy. This leather-wrapped offering from Barbour is classier than most. The flask itself is made from stainless steel, with a healthy 4 oz. capacity and a hinged screw-top lid that won't get lost. The removable waxed leather cover has a branded stud-fastening closure and will gain a unique patina over time, much like its carrier.
