The Koulin Trail carries the slogan ‘wear more, wash less’ thanks to the application of silver-based treatment Polygiene. The body-mapped mesh panels under the arms keep it breathable and odour-free, and the rear pocket is handy for keys and cash – although a zip would make it feel more secure. But at this price, it's hard to fault.
Does what it’s supposed to do at a fantastic price.
The September-October 2018 edition of Trail Running contains plenty more long-sleeve, half-zip tops reviews.
