These men’s thermal underwear trousers are made for work on cold days, with a recommended temperature range of -5°C to -30°C. They combine the moisture transport of a synthetic base layer with the insulation of merino wool.
The fabric is knitted in two layers. The rib-knitted inner draws moisture away from your body to the outer layer, where the fine merino fibres absorb it. This helps keep your skin drier and warmer during long shifts outdoors.
Key features
- Two-layer construction carries moisture from the skin to the outer layer
- Fine merino wool in the outer layer absorbs moisture and adds insulation
- Rib-knitted inner sits close to the skin to help moisture move away quickly
- Elasticated waistband keeps the trousers in place under workwear
- Cuffed trouser bottoms help seal in warmth at the ankles
- External labels keep tags away from the skin
