Don't bother with the "Roadie" sized cooler. It barely holds a 6-pack and a 10# bag of ice and if it does, it's too blooming awkward and heavy to carry with the fold over handle. Go the next size up with the two rope handles.

Yeti coolers are referred to as "Redneck Rolexes". Nobody really needs one, but it allows you to show everyone you have money to blow.
