One of the best parts of Smartwool base layers is that they help reduce some of the uncomfortable distractions intense activity can produce. This crew top features our Intraknit technology—where insulation, articulation, and ventilation are seamlessly integrated to help enhance movement and comfort. The fabric helps combine the moisture management, temperature regulation, and odor resistance of Merino with TENCEL Lyocell fiber to help keep you cool. And with minimal seams to help reduce chafing, this top will allow you to focus on taking your workout to the next level. So go out there and feel good doing it! | Smartwool Men's Intraknit All-Season Merino Base Layer Crew Top in Nightfall Blue | Size: XL
