The Second Skin leggings from Looking for Wild are aptly named, as they are made from a breathable and temperature-regulating fabric made from polyamide and plenty of elastane. The fit is also perfect, with an elasticated waistband, gusseted crotch and breathable perforations in the calf area. There is a bag hidden in the waistband for your keys or other small items. Go running, yoga, climbing & bouldering, all with these leggings.
