In reply to Roberttaylor:
Direct Alpine or Bailo? Also try Think Pink as suggested above. It's quite noticeable that Italian climbing/outdoor shops used to have a good selection of brightly coloured 'patch' trousers made by European manufacturers, but recently everything has become dominated by the worldwide brands like North Face and Salewa and as such the UK-style black/grey trousers have become the norm

I have an awesome pair of patch trousers in one colour by Bula of Norway but they don't seem to make them anymore
