It's very probable that the desert canteens, first aid kits, WWII mechanic sweaters, henleys and backpacks at your local army surplus store were made by Long Island's Rothco. The company started in Manhattan over 50 years ago and is now "America's foremost wholesale supplier of military and outdoor products." Whether or not that's true, I don't know, but they sure do make some damn handsome camping gear. And I'm sure their canteens are BPA free...
