From Trimtex:
"The Trail t-shirt is a durable running shirt. This top is light and quick-drying, very durable and tolerates rough treatment. This makes it great for sports such as cross-country running, track and field and orienteering. It has a slim shape that goes in at the waist and a zip at the neck. The t-shirt is made from a breathable fabric, and there is also a large ventilating panel on the back and under the arms which removes heat and sweat effectively. This allows optimal moisture transfer, which is vital in challenging conditions.
This product has a tight fit. It will fit close to body, but not cling to it necessarily. There is freedom of movement and is a product that will fit most people."
