Shine bright with the 2-in-1 On Lumos Active Shorts.

These lightweight shorts have highly reflective detailing, so you have stand-out style, even when running in low-light conditions. The longer, high-stretch inner tights offer support and distraction-free comfort, while the loose-fit, lightweight shorts give you extra coverage and maximum airflow.

These shorts are Swiss engineered with everything you need for an amazing run. They are fast-drying, breathable and offer next-to-skin comfort. Plus, when the weather gets really cold, you can attach the outer shorts to the On Lumos Tights Long.

Whether you are doing an outdoor HIIT class in the morning or want to run safely at night, the On Lumos Active Shorts give you visibility and performance.
