Since today is the first day of summer, it's a good time to start thinking about how to keep your brewskis cool—and these byobags have a good chance of actually working.
Don't these little insulated carrying cases just scream "take me out to the ballgame?" Might be a good deal, since a nice cold frosty one is going for around $6 at the ballpark these days. But then, it might be kind of hard to sneak one of these byobags into the park, especially since they're so eye-catching and brightly colored.
They're available for a single wine/champagne bottle ($18.50ish) or a sixpack (around $28), and take a look at that convenient carrying handle. You can even pull it down and serve wine right from the bag.
