They're Karrimor and some people seem to think that's not great quality, but these really are brilliant quality. They are pretty long as they're men's and the fabric is thick so they're best for colder days. I also have some of the dark green Trail stuff and it's also fantastic. Super quality for not a lot of money and they do ladies' versions too.
Don't pay any attention to the RRPs though - they're rubbish.
