Need some help!

Look, I realize this probably isn't the most appropriate forum for this particular inquiry, but I find myself in need of some assistance:

Where might one go to purchase a bottle like this in San Francisco,
specifically one equipped with that vacuum-insulated extension designed to keep liquids chilled?
Furthermore, I can't help but wonder if these bottles actually manage to maintain a cold temperature, or if it's all just clever marketing theater.



Much obliged!

You can find plenty of that stuff over in Manhattan, so you should probably take a look there... I think it’ll run you about $17. As for whether it actually works, I honestly couldn't tell you since I haven't personally tried it yet...
