This men’s thermal top is a warm base layer for working in cold environments, with a recommended temperature range of -5°C to -30°C. It is made for long days outdoors or in cold spaces where staying warm and dry matters.
The 100% merino wool insulates well and moves moisture away from the skin, so you stay drier as you work. Extra warmth is placed on the shoulders, arms, back and sides, the areas where the body tends to lose heat first.
Key features
- 100% merino wool provides strong insulation in cold conditions

- Warming zones on the shoulders, arms, back and sides target the areas that feel the cold most
- Rib-knitted construction for a close, flexible base layer
