The Mens Classic Thermal Merino Base Layer Pattern 1/4 Zip Laguna Blue blends upgraded performance with a fresh, modern look. Designed for warmth and comfort in cold conditions, this layer is made from 100% responsibly sourced Merino wool with an interlock knit that offers exceptional softness, breathability, and durability.
As one of Smartwools warmest base layers, it naturally regulates temperature, wicks moisture, and resists odor, keeping you dry and comfortable through intense activity or long days outdoors. The updated fit provides a more refined silhouette without sacrificing mobility, while shoulder panels remove top seams to reduce bulk under backpacks.
Flatlock seams prevent chafing, and the 10″ (25 cm) semi-locking center-front zipper allows for quick ventilation and easy temperature control.
Perfect for skiing, hiking, running, or layering in everyday cold-weather conditions, this base layer combines reliable warmth, performance, and style.
