The Portwest B127 Thermal Base Layer Set pairs a long sleeve top with matching leggings, giving you a full insulating layer for colder working days. Both pieces are made from soft polycotton, worn next to the skin.
The fabric lets your skin breathe, so you stay drier if the work warms you up or conditions change through the day.
