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.
