    This is the best retailer I have ever used and I do a lot of online shopping. My wife and I have purchased a number of items from Cimalp over the last year or two and the items and service are always excellent. I now have 2 pairs of these trousers in different colours as they are fantastic. So versatile. 5 stars

    Very happy. Really slick and smart pair of trousers. Which I will use for trekking, but could be as easily for trail running.
