The Klean Kanteen Insulated Classic Narrow with sports cap 355 mL Unicorns is the ideal drinking bottle to take to school, sports, on a walk or just for everyday use. It comes with a Sports Cap made from soft silicone. It is dishwasher safe, can be opened with one hand and comes with a practical attachment loop, so you can attach the bottle to your bag. This 'Classic Narrow' version is somewhat slimmer than the standard Klean Kanteen Classic. As a result, it's even more comfortable to hold and it will fit in the side-pocket of your backpack. Even though it can still hold 355 mL! The bottle is insulated, so your beverages will remain hot for a long time. And you can even enjoy chilled drinks cold for up to 40 hours!
