The easy-on, easy-off SmartWool Men's PhD HyFi Full-Zip Top is the easy option when winter blows in the first cold front of the season. The merino wool-nylon bi-component jacket holds in heat and addresses your sweat as you slice through gusts of chilly air, so you can keep on trucking all day long. The HyFi fabric's nylon outer face rebuffs chilly winds and resists abrasion, while the soft, breathble merino wool knit on the interior moves sweat vapor away from your skin, making this jacket well-suited for high-output aerobic activities like running or cycling. As a bonus, wool's natural antimicrobial properties keep it fresher than any all-synthetic gear in your athletic wardrobe. And engineered thumbhole cuffs provide just enough protection when the cold's making it hard to get going on an early-morning outing.
