Engineered for Performance

The Portwest B123 Thermal Long Sleeve Top is a critical component for effective thermal regulation in industrial workforce management. Designed to function as the primary insulating layer next to the skin, this garment utilizes a specialized 200gsm poly-cotton fabric construction. The material science behind this blend is key: the polyester fibres provide structural integrity and facilitate moisture transport, ensuring that perspiration is wicked away during periods of high exertion, while the cotton content offers superior thermal retention and softness. This breathability is vital for preventing the 'chill' effect that occurs when sweat cools on the skin in cold environments. Whether for logistics personnel in unheated warehouses or construction teams facing winter elements, the B123 ensures that core body temperature is maintained within optimal parametres. By issuing these baselayers, businesses can directly contribute to the health and safety of their staff, reducing cold-stress related fatigue.

Comfort & Workforce Utility

Employee compliance with uniform policies often hinges on comfort, and the B123 excels in this regard. The garment features a traditional t-shirt cut but with extended long sleeves that are finished with durable cuffs. These cuffs are engineered to stay in place, preventing the sleeves from bunching up when outer layers—such as fleeces or heavy jackets—are put on or taken off. The round neck design is low-profile, ensuring it remains invisible under standard polo shirts or corporate uniforms, maintaining a professional appearance while providing hidden warmth. The fabric is soft to the touch and free from abrasive seams, making it suitable for all-day wear (8-12 hour shifts) without causing chafing or irritation. As a unisex garment with a generous fit, it simplifies stock management for procurement managers while ensuring every team member, regardless of build, has access to essential thermal protection.
