KNOX Dual Active Base Layer Long Sleeve Shirt Grey

The Knox Dual Active Base Layer Long Sleeve Shirt is designed as the essential first layer for riders who demand year-round comfort, performance and moisture management. Worn directly against the skin, it creates the perfect foundation beneath protective motorcycle apparel and technical sportswear.

Constructed from a premium polyester and spandex blend, the shirt delivers a luxuriously soft feel while maintaining excellent stretch and unrestricted mobility. Its lightweight and breathable structure allows complete freedom of movement throughout every ride.

Advanced HYDROCOOL® technology actively draws moisture away from the body, accelerating evaporation and helping to regulate body temperature. This keeps the rider feeling dry, comfortable and focused, even during demanding rides or warmer conditions.

To maintain lasting freshness, the fabric incorporates SILVERPLUS® antibacterial treatment. This technology helps prevent the growth of odour-causing bacteria, reducing washing frequency and extending the life of the garment.

Strategically positioned die-cut ventilation zones beneath the arms and between the shoulder blades maximise airflow where it is needed most. Bonded seams and reduced stitching create an ultra-flat profile that eliminates bulk and pressure points beneath armoured riding gear.

The tailored slim fit is enhanced by curved bonded sleeve seams, subtle mountain-inspired graphics and refined Knox branding. These details create a technical yet sophisticated appearance suitable for both riding and active lifestyles.

Whether worn under a Knox armoured shirt, motorcycle jacket or during other sports activities, the Dual Active Base Layer Long Sleeve Shirt delivers premium comfort, breathability and performance in every season.
