Smartwool 2020 Men's Merino Sport 250 Wind 1/2 Zip Baselayer Top

The wind is howling, snow is falling, and the temperature is dropping. Sounds like a perfect day for a run or skate-ski in our Men's Merino Sport 250 Wind 1/2 Zip. Our warmer Merino/poly blend helps move moisture, dries quickly, and holds its shape during high-sweat activities in colder weather. A windproof front panel helps provide increased protection against the elements, while integrated thumbhole openings allow you to really dial up the warmth, even if the weather is working against you.
