Thermal leggings are the ideal choice of bottoms for heading outdoors in when it’s cold. They’re made of material that traps heat and therefore keep your legs warm. Some thermal leggings are fleece lined and others are made out of cotton-polyester blend that is both moisture-wicking and breathable. They are ideal for going for a run on a chilly morning or perfect for walks or hikes.
Thermal base layer leggings can be worn beneath your top layers of clothing to keep your body warm, especially during freezing winter temperatures. Made from fabrics such as merino wool, to protect against the cold, thermal base layer leggings also trap body heat to provide warmth.
We’ve searched the market to find the best thermal leggings for women and men, plus the best selection of thermal base layer leggings for wearing underneath clothing.
