Kleen Kanteen has made all sorts of containers. Camping is a focus. As is hiking. But they have also worked craft beer in there as well. Growlers being one item they do.
But for those who hate red plastic cups. Either due to a horrible country song or because they offend your inner beer geek. Now you can go stainless.
I assume these are primarily for hiking. Why else would you need to buy stainless steel cups?
I assume that they are for the nature types who are also craft beer fans. And rather than drinking from the bottle, they should have an option for from a glass drinking.
