I am not sure about kesh trousers, but if you can get a set of playing pants make sure you can move well in them, I know that as a Marshall you will want something pretty thick, but baggy is just as effective if not more as it cusions the blow from the ball, prob best getting a second hand set off here and trying them, the last thing you want to do is go and buy a set for £50-£60 and be unable to move properly
