Klean Kanteen Caps - Klean Kanteen Classic bottles have three different cap styles: Sport 3.0, Loop and Flat. The revolutionary Sport Cap 3.0 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.Klean Kanteen Wide caps are designed to fit the universal thread design of our wide-mouth bottles. They have stainless steel on the inside of the cap, creating a 100% stainless interior and are available in three styles: Loop, Flip D-Ring and Café. The Loop Cap comes standard on all wide bottles and has a strong, easy attachment point. The functional, space-saving Flip D-Ring transforms instantly from a flat cap to a loop cap, while the Café Cap allows you to convert a Kanteen Wide Insulated bottle (or a regular Wide bottle) into a splashproof to-go mug with a quick twist.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 stainless steel, the Flat and Loop caps are available in a stainless steel version for Klean Kanteen Classic bottles.
