We asked pro trail runner what he would wear as an everyday shirt for shorter training runs. The resulting Trail Half-Zip Short Sleeves Top for trail running is a versatile all-rounder for running through the hills, or in fact any sports activity requiring a highly-functional, comfortable and stylish shirt. The seamless, loose-fit design over the torso allows total freedom of movement with zero chafing. The microfibre material is soft, ergonomic and highly functional.
