On several occasions and also on a 14-day high tour from hut to hut had these pants in continuous stylus. From sub-zero temperatures with below solid long pants to warm 30 degrees it has never let me down! Very stable and not a hindrance by the specially-shaped knees when climbing. In warm weather, the full-length zip at the side is perfectly suited for regulating. Toll is also the integrated gaiters: This saves weight again! The yellow is bright, as shown. The only downside: Other materials (with me the harness) rub off quickly. The size will fit as specified.
