The Comfort Long-T from On is a casual, quick-drying long-sleeved t-shirt for before, during and after runs. Works as a standalone top or as a base layer. Easy. That’s the best way to describe the Comfort Long-T. Easy to wear. Easy to move in. Easy to choose for before and after the run thanks to its innovative mix of wool and performance material – and its stylish appearance. Comfort should be something simple.
