What is stainless steel?
Stainless steel is an iron-containing alloy made from some of the basic elements found on earth.
Why is stainless steel better that aluminum?
Aluminum is light weight and has to be lined to make sure the contents are safe for drinking. Usually it is lined with baked on epoxy which is toxic or ceramic which can crack.
Why is the sports cap made of plastic and not stainless steel?
We chose polypropylene #5 because it has no known leaching characteristics and is softer if you hit a bump on the trail on your teeth. A stainless steel screw-on lid is available if you'd rather avoid plastic altogether.
