Portwest thermal underwear for cold working days

Portwest thermal underwear provides a base layer beneath your everyday workwear when temperatures drop. Worn close to the skin, it helps retain warmth without relying solely on a heavier outer jacket. Consider whether you need coverage for your upper body, legs or both, depending on your working conditions. Explore the wider Portwest range when putting together your work outfit.

Choose a fit that works beneath your clothing

Portwest thermal underwear should sit comfortably beneath your clothing without bunching at the waist, knees or elbows. Check the individual size guide and material details before choosing, and allow enough freedom for bending, reaching and kneeling. Pair your base layer with Portwest work trousers or wear it beneath Portwest coveralls, checking that the combined layers do not restrict movement.

Build a practical cold-weather outfit

Portwest thermal underwear is one part of a layered outfit, not a replacement for suitable outerwear. Add an insulating mid-layer when needed, then choose Portwest work jackets suited to the weather and your tasks. Select Portwest footwear separately for the conditions underfoot. Follow each garment's care label to help preserve its fit through regular washing.

Portwest thermal underwear is worn as a base layer beneath your workwear. Choose a comfortable, close fit that does not restrict movement, and add mid-layers and outerwear according to the temperature and your activity level.
Before choosing Portwest thermal underwear, check the individual product's size guide, material details and care instructions. Consider which areas of your body need extra warmth and how the base layer will fit beneath your usual work clothing.
Wash Portwest thermal underwear according to the care label on the individual garment. Washing temperatures, drying methods and other care requirements can vary by material, so check the instructions before laundering.
