Holding a cold beverage is a leading cause of frostbite, and a less embarrassing cause of frostbite to tell your doctor about than tickling a snowman. Keep extremities extra warm with today's Groupon: for $15, you get a Scandinavian koozie from Sküüzi (a $29.99 value).

The skilled folks in the Wool Craft Union, a fair-trade organization, hand-make Sküüzi's mittenesque beverage holders from cozy Merino sheep wool. A functional garment originally designed in the Land of Fire and Ice, the Sküüzi cradles a chilled can of soda, bottle of beer, or jar of fermented shark meat while warmly wrapping the wearer's drinking appendage in a stylish knit sleeve. Available online only in heather gray or light brown, this clever cup holder keeps both right and left paws toasty at bonfires, tailgating parties, or camping trips inside walk-in refrigerators.
