Cowhide Koozies. Quite possibly the coolest koozie ever made! Now there are quite a few folks out there makin' koozies outa cowhide & leather and all sorts of other skins, but the quality of these is far superior to all the others we've had the pleasure of sippin' cold beverages from. They start with some beautiful and diverse pieces of hide and hand-stitch the hide to some high-quality neoprene, creatin' a sorta little cozy scuba suit for your beverage of choice. These babies will keep a beer 40° or below for 35 minutes. If ya need longer than that, you may wanna get a nipple for your beer instead. The koozies are structured with cutaways at the base so you can easily flatten the lil' suckers and stick 'em in your back pocket and then you're off to the rodeo/tractor pull/mullet toss...or wherever a freebird like yourself may roam.
