Why choose the Workforce Heat Holders Thermal Long Johns?

Covering the upper body alone leaves your legs exposed to the cold. The Workforce long johns complete the first thermal layer for the lower body in the same logic as the top: 52% polyester for durability, 48% cotton for softness, a functional fly for everyday wear, and sizes from XS to 5XL to fit every build, down to −20 °C / −4 °F*.

The three-layer system — the basics of dressing for severe cold:

1st layer — base (role of this product): next to the skin, it holds body heat and limits chafing under work trousers
2nd layer — mid layer: insulates and holds warm air around the body — fleece trousers, thermal overtrousers
3rd layer — outer layer: protects against wind, rain and snow — ski trousers, waterproof overtrousers, cold-weather bib overalls

* Indicative temperature. Perceived warmth varies with activity, body type, humidity, wind and the layers worn underneath.
