Part of the Lumos Collection, these tights have highly reflective detailing that offers outstanding safety and stand-out style. They are made from a new, high-quality brushed fabric that keeps your legs warmer, for longer, even over longer distances. Pockets on the rear plus a key loop help keep all your essentials safe, so you can focus on nothing but the run. By using the modular connecting system, you can attach other On products, such as the Hybrid Shorts. Move and be seen in style and comfort in the On Women's Tights Long Lumos Leggings.
