Description
Additional information

The Portwest B123 is a long sleeve thermal base layer for outdoor work in cool weather. It holds warmth close to the body and keeps the arms covered through long shifts.

The fabric lets the skin breathe if you warm up during physical tasks, so it stays wearable as conditions change through the day. A round neck makes it easy to wear beneath shirts, fleeces and jackets.
