The Guru Polar Joggers in Black are cold-weather trousers built on the popularity of the classic Black Joggers, with a serious interior upgrade. They are crafted from a moisture-wicking one-sided brushed fleece and feature an internal sherpa fleece lining that traps heat while remaining lightweight and breathable. Substantial enough to serve as a warm outer layer like traditional joggers, they can also function as a versatile underlayer beneath bib and braces or waterproof outerwear. The Polar Joggers are available in Black and Grey, and in sizes from XS to 4XL. - Materials: 100% polyester
