If long johns are overkill in your neck of the hemisphere, look to Sartoria’s adorable woolly undies . Each pair is handmade to order in the Great White North—where people really know frosty weather—from upcycled merino-wool and cashmere sweaters. They’re available in four sizes and your choice of rise, with plenty of options for the menfolk, too. Looking for something a little racier? Sartoria’s upcycled garter belt will send thermostats soaring.
