From Trimtex:
These Trainer Pants are light and versatile training pants with a wind and water-resistant fabric at the front and a breathable and stretchy material at the back that makes the pants flexible and comfortable to wear, even during larger movements. As well as the breathable material at the back, the pants also have ventilation below the knee.
The upper part of the pants also has a mesh lining to make them more comfortable when you get sweaty. These features make the training pants suitable for a slightly higher activity level, such as running, shorter hikes and other exercise. There is also a zip on the leg, an elastic waistband with a drawstring and one-handed adjustment, a zip pocket on the right side and reflective details for improved visibility.
