Smartwool Men's Merino Base Layer All Season Long Sleeve Shirt 1/4 Zip

Zip up when it's cold and unzip when it's warm—that's our Classic All-Season Merino 1/4-Zip Base Layer Top. This top features our year-round merino fabric with a nylon core for increased durability and 100% soft merino wool that you'll love against your skin. Side seams reduce chafing when carrying a pack and offer a body-sculpting fit. Select colorways are created using a more responsible plant-based dye technique. This base layer is comfortable, high-performance, sustainable, and, frankly, a do-it-all.

Our slim fit is characterized by a close-fitting cut.

Our lightweight merino jersey fabric features a recycled nylon core for enhanced durability, while pure merino wool on the inside provides soft comfort.

Flatlock seams and offset shoulder and side seams provide better comfort and reduce chafing

Side seams running forward for a figure-hugging fit
