Long-sleeve T-shirt On Running Performance Long-T Lumos

The On Performance Long-T Lumos is built for runners who want lightweight comfort and extra confidence when training in low light.

If you are looking for a men’s long-sleeve running shirt that delivers breathability, freedom of movement, and standout reflective performance, the Performance Long-T Lumos is a strong choice for every mile after dark.
