For eco-aware hikers: This fashionable and lightweight short-sleeved blouse is extremely well ventilated and extremely quick-drying thanks to the mesh material on the back. The stretch content is superbly comfortable, especially on demanding hikes. The material ("cooling print") on the inside of the fabric supports the body's own cooling process when it’s hot out. An ideal functional shirt for warm climates. The VAUDE Green Shape label stands for environmentally-friendly, functional products made from sustainable materials.
