These guys are in Wilmington, NC and their product, FREAKERS, rocks. It keeps cold cold and hot hot. It fits just about anything you can drink out of and they are customizable, so if you have a business and you are looking for branded, cool things to sell or give away as promotional items, this is it. It’s the killer cozy. Love these things. I got the surfer and the Sasquatch version at the show. I might order some for the Mullet.
Check them out at: Freaker USA
They also have a Kickstarter Campaign for their Sock line: Freaker Feet. Hook them up and get your toes toasty.
