This foam sleeve is guaranteed to chill your can or keep your can chill. That’s not a euphemism. We literally mean our Hopslam® Can Cozy will keep your can of Hopslam nice and cold. (Also works like a charm on any other can, as long as it’s 12 ounces and one of ours. We have a lot of amazing cans that deserve this amazing little jacket.) Buy two and use them as emergency mittens. Or better yet, emergency hand puppets.
