Now, most people who want to buy a pair of walking trousers do so because they're active right? And when you are active, you tend to have more defined muscles. I'm an avid cyclist and walker, and so my thigh musles are quite well defined, but not massive, so when I bought these, I couldn't believe that the zips on the trouser legs allowing you to convert these into shorts were so tight I couldn't get them past the middle of my thighs. The rest of the trouser were plenty big enough, if not just a little too large. I'm sorry Craghopper, but this is ridiculous. I couldn't even get them over my thighs as shorts. I'm not a body builder, my thighs are a normal size, but your trousers are not!!
