This long sleeve thermal t-shirt is a women’s base layer for work in cold conditions. It insulates to keep you warm through the day, and the fabric lets your skin breathe if you warm up during active tasks or move indoors.
A round neck and long sleeves make it easy to wear beneath shirts, fleeces and jackets. It is designed specifically for women, so it works well as an under-garment beneath your usual workwear.
