These tech fleece joggers are made from recycled water bottles and spent coffee grounds: Each pair contains 10 of the former and 3 cups of the latter. A waterless dyeing process saves millions of gallons of H2O, and their water-resistant, UV-protective finish is created without chemicals that can wash off and cause trouble in our water systems.

Does all this mean they look and feel weird? Yes: weirdly wonderful. Fluffily fleece-like, soft, warm, and lightweight, they might be the comfiest pair you've ever put on—or slept on, when you pack them up to use as a pillow on the road.
