18/8 Stainless Steel – Why stainless? It’s safe, durable, doesn’t react with other chemicals (like aluminum does) and doesn’t absorb, impart flavors, or leach who knows what (like plastic does). 18/8 stainless steel—the same material used in industrial kitchens and hospitals—is completely free of BPA, lead, phthalates, and other toxins.

5.6" H x 3.8" W (141.5 mm H x 97.5 mm W)

Opening Diameter – 3.08" (78 mm)

Corrugated Recycled Cardboard Insulation in Lid – Hemetically sealed to keep out moisture and performs comparably to foam insulation, but is much more eco-friendly.

Easy Clean – Klean Kanteen's focus on health doesn’t stop with the materials they use. True to their name, Klean Kanteen makes products that are easy to clean—and keep clean. All bottles, cups, and canisters feature rounded corners, large-mouth openings, and large-radius threads, so there are no hard angles that allow germs and bacteria to hide out inside.

BPA Free – Klean Kanteen has been free of Bisphenol A (BPA) since the very beginning. Klean Kanteen's vessels are stainless steel inside and out (no plastic liners necessary), their lids are stainless and/or BPA-free polypropylene #5, and they use medical-grade silicone for their gaskets and baby products.
