Klean Kanteen® Classic bottles have three different cap styles:
Sport 2.0, Loop and Flat.
The revolutionary Sport Cap2.0 effortlessly delivers a high flow rate that makes it easy to drink from your bottle without removing the cap. The Loop Cap is totally leakproof and has a durable attachment point so you can clip it on to just about anything. And the Flat Cap is low-profile, unobtrusive and leakproof.
All Klean Kanteen® caps are made from polypropylene, a safe plastic that's free of BPA, phthalates and other toxins. But if you want to be sure your drink never touches anything other than food-grade stainless steel, the Flat and Loop caps are available in a stainless steel version for Klean Kanteen® Classic bottles. Order the Stainless Flat Cap or the Stainless Loop Cap.
