Description
The Portwest thermal base layer leggings (B135) are a functional undergarment that retain heat and wick away moisture when working in cold conditions. The leggings are made from 100% moisture-wicking polyester (140 g/m²) and are designed to be worn as a first layer under workwear. They are suitable for women working outdoors or in unheated spaces who need thermal support without bulky extra layers.
For what type of work or industries are the Portwest B135 thermal base layer leggings suitable?
The B135 is suitable for anyone working in cold work environments who needs lightweight, heat-retaining base layer under regular work trousers.
This includes outdoor work in construction, landscaping, logistics, or security, as well as work in refrigerated storage areas or warehouses. Because the leggings fit closely and do not bunch up, they fit comfortably under almost any pair of work trousers. The moisture-wicking polyester draws sweat away from the body, keeping the wearer dry and warm during active work.
When should you choose the B135 thermal base layer leggings instead of standard undergarments?
Choose the B135 when you need a base layer that actively helps regulate temperature and manage moisture, rather than simply serving as an extra layer.
Standard cotton undergarments absorb moisture but do not wick it away, which can quickly leave you feeling cold and clammy during physical activity. The B135 is made from 100% moisture-wicking polyester, which draws moisture away from the skin and retains heat. This makes them more suitable for active outdoor work or work environments with fluctuating temperatures, where staying comfortable and dry throughout the working day is important.
The leggings can be washed at a maximum of 40°C on a mild cycle and must not be tumble-dried or ironed.
