When the day goes from cold to hot, turn to the temperature-regulating comfort of the Smartwool Men's Merino 150 Pattern Hoodie. Crafted from a stretchy merino wool blend, this pullover wicks sweat and dries quickly to provide dry comfort during hotter days, while trapping body heat for warmth in chillier climates. Plus, the natural anti-odor attributes of merino wool help keep funky smells at bay when you head to the restaurant after hitting the trail.
