Small and lightweight, the 355ml / 12oz Klean Kanteen Classic is great when space is limited. It's the perfect size for juice and other naturally sweet drinks, rumor has it that grown-up Klean Kanteen fans commonly use it as a flask, and with adapter and Avent Sippy Cap, it converts to a safe, BPA-free sippy for kids.

Weighing just 4 ounces, its compact size allows you to take it almost anywhere. Tuck it in your purse when you head to the store. Throw it into your jam-packed messenger bag on your way to work. Toss it in your backpack for a quick hike or a trail run. Keep the kids happy with an easy-to-hold, spill-proof drink at lunch. It's a versatile option for kids and adults.

Food-grade stainless steel is used in the brewing, food and winemaking industries too. It's the material of choice because it doesn't retain or impart flavors. All Klean Kanteen caps are BPA-free too, and we offer stainless steel options for Classic bottles as well.

For additional loop caps or sport caps for your Klean Kanteen bottle, these can be purchased from VUPbaby.

Available is the following colours: Red, Green, Black, Stainless steel and Ocean Blue.
