Why is the sports cap made of plastic and not stainless steel?
Your teeth. Polypropylene #5 has been chosen because it has no known leaching characteristics and is softer if you hit a bump on the trail. If you’d rather avoid plastic altogether, a stainless steel screw-on lid is available as an accessory.

What is stainless steel?
Stainless steel is an iron-containing alloy made from some of the basic elements found on earth: iron ore, chromium, silicon, nickel, carbon, nitrogen, and manganese. Properties of the final alloy are tailored by varying amounts of these elements. There are more than 57 stainless steels recognized as standard alloys on the market. Klean Kanteens are constructed from high quality sanitary grade 304 stainless steel which has a low nickel content. Stainless steel has excellent resistance to stain or rust due to its chromium content making it a material of choice among the food processing, dairy and brewery industries. Stainless steel is easy to clean, durable, inert and sanitary.

Will the stainless steel react with acidic beverages?
No.
