BottleKeeper

Nothing is more rewarding than some ice-cold suds following a long, scenic hike, and with BottkeKeeper you can do just that. The clever, insulated contraption looks like a regular flask but fits around your beer bottle keeping it cooler and fizzier for longer. Also protects the glass and sports a screw-on lid meaning you can re-seal an open brewski–ideal for backyard barbecues and get-togethers on the beach as well.
