    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 fast delivery, quality pants, looks like a mesh but with the firmness of a pant, the size I always use, 1.70 and 61kg and I took the size S and perfect.

    Very happy, very comfortable, they fit great and look great, I had ordered from another winter brand but I'm so happy that I'm going to change them and try these too.
