Patagonia Nano Puff Scarf
We're not about to say that it's the most stylish scarf out there, but it might be the most durable. The Patagonia Nano Puff Scarf ($50) features a wind- and water-resistant Alpine Nano Puff shell, lightweight 100-g PrimaLoft One stuffing for heat retention, and a pass-through slit to keep it snug against your neck. Available in the always serviceable black or a light gray fog that'll be noticeably trickier to pair properly.
