Thermal Baselayers for Work
A thermal baselayer is the layer that decides whether a winter shift is comfortable or miserable. Worn next to the skin under workwear, hi-vis or FR outer layers, it traps a layer of warm air and wicks sweat away so you stay warm when standing still and dry when working hard.
Baselayer tops, leggings, trousers and full sets designed to sit close to the skin under work trousers and jackets, adding warmth without adding bulk that restricts movement.
Thermal knits move sweat away from the skin so it can evaporate. Staying dry matters as much as insulation, because damp fabric pulls heat from the body fast in cold air.
Beyond the classic thermal tops and leggings there are merino wool styles for natural odour control, antibacterial Base Pro knits for long shifts, and women's fits across the core lines. 19 baselayer lines are available.
Free UK delivery on orders over 75 pounds, with sizes to kit out a whole crew before the cold sets in.

About thermal baselayers for work
Outdoor trades lose heat two ways: to cold air when standing still, and to damp clothing when working hard. A work thermal baselayer answers both. The brushed inner face traps a layer of warm air against the skin, while the knit wicks moisture outwards so sweat does not sit against the body and chill it during breaks. Because the layer is thin and stretchy it fits under existing work trousers and jackets, so a crew can winterise the kit they already wear rather than buying heavier outer garments.
Choose the fabric by the shift. Classic polyester and viscose thermals are the workhorse choice for site, yard and delivery work. Merino wool styles control odour naturally across long stretches between washes, and the Base Pro antibacterial knits do a similar job for laundered programmes. A short sleeve top suits milder days or heated cabs, long sleeve tops and leggings cover full outdoor days, and a top and trouser set is the simple way to issue a complete layer. There is also a flame resistant knit legging for wearers who layer under FR clothing.
Baselayers pair naturally with the winter lines across the rest of the catalogue, from insulated hi-vis outer layers to cold-rated gloves sold at pack rates. Browse the full range on the products page, or read how the workwear standards fit together in our safety standards guide.
