The Tna TnaRENEW™ Atmosphere Hi-Rise 7/8 Legging is a high-rise legging with recycled materials. Sustainably so. These are high-rise leggings with our signature wide waistband for a smooth silhouette. They’re made with TnaRENEW™ — an ultra-stretchy, soft and supportive jersey made with recycled materials. For more responsible runs/rests.
