Its a tradition as old as fly fishing itself. When the need arises to wet your whistle (as it invariably will), your Wetfly Flask cheerfully delivers. Made of rugged, food-grade 18/8 stainless steel, the Wetfly Flask holds 7 oz., or about 4 good shots worth, of liquid refreshment enough to take the edge off a tough bite and reassure an angler and his partners that all is indeed right with the world. Contoured to fit comfortably in a hip pocket. Includes manufacturers lifetime warranty. Cancer and Reproductive Harm- www.P65Warnings.ca.gov.
