Knox Dual Active Base Layer Long Sleeve Functional Shirt
The Knox Dual Active Base Layer is the perfect first layer in the Seasonless® Collection and is worn directly on the skin. Designed for year-round use, it ensures a precise fit, high wearing comfort, and effective moisture management. Worn under a Knox Armored Shirt, it prevents heat build-up and unpleasant stickiness—but is also ideal for other sporting activities. Completely redesigned for 2026, the Dual Active Base Layer is made of fine, breathable polyester with stretch. The material feels soft, offers maximum freedom of movement, and remains comfortable on the skin even during intense activity. Bonded seams and reduced stitching zones ensure a flat, pressure-free feel under other layers.
Technical features from Rudolf optimize performance: moisture is quickly wicked away from the body, while an antibacterial finish reduces odor. Perforated ventilation zones under the arms and between the shoulder blades further improve air circulation. The long-sleeved men's model impresses with its slim cut, ergonomic seams, and high-quality finish on the collar, cuffs, and hem. Subtle graphics and understated branding round off the technical look.
