On was created with the intention of bringing the wild back into running - primarily, through the Swiss Alps and making it more accessible. But when it comes to exercising in the mountains, you need the right gear. The Lumos Performance long-sleeve T-shirt is a lightweight layer to wick away sweat, regulating body temperature through the minuscule perforations on the back.
