Knox Dual Active Base Layer Women's Long Sleeve Functional Shirt
The Dual Active Base Layer for women is the perfect foundation for the Knox Seasonless® Collection. Designed as the first layer directly on the skin, it combines a feminine fit, luxurious comfort, and technical performance—for every season and every activity. The version revised for 2026 is made from a particularly fine polyester-elastane blend that feels soft and smooth while offering maximum freedom of movement. Thanks to bonded seams, the base layer sits flat and close to the body without pressure points or unnecessary bulk – ideal under a Knox Armored Shirt or on its own for sporting activities.
Modern Rudolf technologies ensure that you stay dry and fresh even in hot weather or under high stress: moisture is quickly wicked away, odor formation is reduced, and the skin climate is optimally regulated. Additional ventilation zones under the arms and between the shoulder blades noticeably improve air circulation. The feminine, tailored cut with subtle design details and elegant Knox branding makes the Dual Active not only functional but also stylish – a base layer that effortlessly combines performance and elegance.
