Grizzly Wool Pants Men are both functional and comfortable pants in a lovely sweatshirt material made of Merino wool and Lyocell. The Merino wool is both warming and very soft, and is of course mulesing-free. The wool has naturally warming properties and is also good at wicking moisture away from the body. Lyocell is a fiber that is both durable and a more environmentally friendly alternative to conventional cotton. The inside of these sweatpants is brushed, making them extra soft and comfortable. Pockets on each side. Fits perfectly as a first or second layer under shell pants, depending on how cold it is outside. Swedish-manufactured fabric, sewn in Europe.
