A 40 oz stainless steel tumbler built to be filled once in the morning and carried all day. Double-wall vacuum insulation keeps cold drinks cold for up to 24 hours and hot drinks hot for up to 12 hours, so the ice is still there at 4pm.
The lid takes a flip straw and closes leak-proof, which means it travels in a tote bag rather than being carried upright across a car park. The tapered base is sized to drop into a standard cup holder, and the moulded handle gives you something to hook a finger through on the walk in.
