Comes in several colours as well as silver stainless. Available at Costco (in Canada) in a 2 pack for around $20.

I used this with tea for winter riding and it worked great. My wife uses one as water bottle - ice cubes stay frozen for an hour at 80 F & she can use it one handed on her bike or driving.
