...for the guy that has everything.

My son spends his day driving around NYC & Westchester county hawking wine to country clubs. I was thinking of something like this as a gift but the one above is not in production. Personally I drop the cup inside a roll of duct tape, but it's hard to reach on the passenger floor.
Got a holder that works well? Lemme know.
Thanks, Dan
On the passenger's floor of the Miata, I have one of these powdered Gatorade containers. Inside is a Ziploc bag full of BBs. It never tips over.

You can fill a CamelBak hydration pack with coffee.

or a coolshirt with iced coffee and have a bypass valve to a straw. It works great for enduro racing, until a code brown, then it becomes code very brown.

I'm not sure if this coffee cooling shirt of yours is lunacy or pure genius.
On a side note... I just added a circuit to my motorcycle for the cool shirt cooler. It was 88F and humid last weekend and I got stuck behind an accident that closed the highway. Many pounds were lost baking in all my gear until I could get clear of it. Next time... I'll be too chilly.

genius for early morning sessions and sprint races, anything beyond 45 minutes and it's a terrible, terrible idea.
