A good work base layer is the cheapest upgrade you can make to winter workwear. Worn next to the skin, thermal base layers trap warmth while wicking sweat away, so you stay dry on a cold scaffold at 7am and don't overheat once the graft starts. They're thin enough to wear under any uniform, with none of the bulk of an extra fleece to catch on tools. Order online in minutes, or talk to a named specialist if you're weighing up fabric weights for outdoor trades versus chilled indoor work. Kitting out a team? Decoration on your workwear is a flat £4.00 per logo per position, embroidery or print, with no minimum order.
