The new Aspect Base Layer bottom that is the next evolution of our original Ridge Merino Inversion Midweight. The Aspect pant offers the same great-fitting, sweat-wicking, breathable and odor-resistant qualities and feel great next-to-skin. They will keep you warm, dry and comfortable all day long. This time, we’ve amped up the technical performance features by incorporating our (m)Force Technology, a nylon core-spun Merino wool, to achieve industry-leading durability.
