Best quality bottle container that keeps liquids COLD?

[Ray Jackson]

I'm going to be outside a lot this summer and I need something that I can bring my veggie/fruit smoothies in and be assured that it will stay cold for at least a few hours at a time. I know I can find something like this at Walmart or Amazon or wherever, but I want the best.

Unless it costs a ridiculously amount of money and I have to return to the streets as a male prostitute to pay for it.

...those days are over for me.
