B123 - Thermal T-Shirt Long Sleeve

The Portwest B120 Thermal T-Shirt is a short-sleeved base layer with a round neckline and comfort fit. Its 200gsm fabric combines equal proportions of polyester and cotton. Designed as an additional thermal layer, it can be worn beneath everyday workwear when extra warmth is wanted without adding a long-sleeved undergarment. Choose the size and colour options shown for this product, and compare garment measurements with your existing layers before ordering. Consider the full clothing system and working conditions when selecting thermal workwear. Follow the garment label for care: Portwest lists a maximum 40°C gentle wash, no bleach and no tumble drying. If adding branding, confirm the process and care instructions with your decorator before production.

Select a size that sits comfortably under your outer trousers without restricting movement at the waist or knees. The page offers several colours and sizes from XS to 4XL. Match the whole clothing system to the temperature and activity, and follow the garment label for washing and drying.
