Flat Cap

Klean Kanteen® Classic: Flat Cap
Designed to give you a low-profile option that doesn’t take up much room, the Flat Cap is also our lightest weight cap. It’s the choice for itty bitty purses, jam packed bags or those times when you want a smooth, simple look. Of course it’s also made from polypropylene (pp#5), so it’s free of BPA and other toxins.
