    Bought 3 pairs of walking or trail trousers as presents for children. Great delivery to UK despite border chaos. Trousers seem good so far, well made and robust. Fit to size, if anything the cut is slim but the kids like this. Fully recommend

    Very nice pants, very comfortable to wear, very well finished. Very good quality. The size is perfect.
