Knox Shirt Men's Dual Active Base Layer Long Sleeve Black

The Men’s Dual Active Base Layer Top combines cutting-edge design with all the technical features of the Dual Active range, making it the ultimate first layer for year-round riding. This long-sleeve style offers a relaxed yet slim fit, balancing comfort and performance perfectly. Engineered with fewer stitched seams and more bonded seams, including curved seams over the sleeves, the top delivers a clean finish at the neck, cuffs, and hem. The bonded finish reduces bulk and eliminates seam pressure points when worn under other layers, providing a smooth fit. Die-cut holes under the armpits and between the shoulder blades improve airflow, enhancing breathability and moisture control in key sweat zones. The subtle mountain print on the front and lower sleeves adds a signature Knox touch, while sleek Knox branding ensures a modern, stylish finish. Finished with premium Rudolph technologies, the fabric incorporates Hydrocool® for superior moisture management and quick drying, along with Silverplus® treatment for long-lasting antibacterial protection. With advanced fabric technologies and thoughtful design, the Men’s Dual Active Base Layer Top offers optimal temperature regulation, freedom of movement, and comfort on every ride. It is available in Black and Light Grey. Sizes: S – 3XL
