The long running changing trousers are in a semi-fitting design. Dual-fabric construction characterises these trousers: the front legs with specially shaped knee areas and back calf panels are made from warm three-layer membrane Zerowind material or Softshell material that is resistant to wind and moisture. Belt and upper part of back legs are made from very stretch and soft Roubaix material for better breathability and full range of motion. Trousers are anatomically shaped and this can be enhanced by a waistband with a drawstring. There are also two zip pockets in the front with lock down system. Long underlaid and water-resistant zips along almost all length of the legs make them versatile and ready to be used before and after sport activity and makes them easier to put on while wearing boots. Lower turn-ups are finished with edging elastic. Distinctive reflective details are at the back.
