You all ought to offer a titanium double wall, or copper vaccum insulation to the flat, flask style canteens. I am desperately looking all over the market, and there is not one single option for an outdoor, classic style like a large canteen/flask in 1 quart/liter or so that is also double walled or copper vacuum insulated. They are only single walled. Stanley offers a hammertone green canteen that has a decent finish, but it isn't insulated whatsoever except for the outer finish being quite nice.
What is with every single company only selling cylinder shaped recepticles as insulated? I'm sick and tired of carrying an uncomfortable cylinder around when I adventure. I would purchase a Spanish bota bag wineskin, but the latex and goatskin won't keep my water cold in the heat.
Please fill the void in the market. Such folly that nobody offers this. Just imagine a powder coated or hammertone green coated, copper or titanium vacuum insulated, flat or slightly curved but generally flat canteen for hiking or anythinng at all. Have you ever heard of a better sounding water receptacle in your life? I haven't. The only contender would be a bota bag style but made of copper/titanium and finished with the goatskin outside and a wider mouth since it won't squeeze.
