Every adventure starts with a solid foundation, and so does your outfit. Whether you're in Tennessee or Timbuktu, the ultra-comfy and durable Merino fabric used in the Smartwool® Merino Print Boxer Briefs helps regulate body temperature, manages sweat, and resists odors. Their flatlock seam construction is designed to help increase comfort and minimize chafing, while the lightweight Merino jersey fabric uses a recycled nylon core to increase durability while still keeping Merino wool next to the skin. These printed briefs feature a Merino-lined elasticized waistband for maximum comfort. They have a fully functional fly and offer a slim fit that is intended to follow the contours of the body.
