Thermal Base Layers

Thermal work underwear

Thermal underwear is the first layer of your cold-weather system: it retains body heat and wicks sweat away from the skin, so you stay dry even while working. It is essential for outdoor winter work, unheated warehouses and cold stores, under garments certified for cold.

Merino wool or technical fabric

Merino wool stays warm even when damp and limits odours, suited to long shifts. Synthetic technical fabrics dry faster and are recommended for intense physical activity; some versions are antibacterial. Our range includes long and short sleeve tops, crew neck or zip neck, hooded tops, leggings, long johns and top-and-leggings sets, including women's.

EN 14058: Classes 1 and 2

Some garments are certified to EN 14058, the standard for cool environments. The class indicates the level of thermal insulation: Class 2 insulates more than Class 1. For temperatures below -5 °C, thermal underwear should be paired with outer garments certified for severe cold.

How to complete the kit

Over the underwear add a mid layer, such as a work fleece, and on the outside a winter jacket. For head and neck there are beanies and balaclavas.
