I'm very fond of my moleskins - they're cherry red, and my daughter will not walk within 20 yards of me when I'm wearing them! Honestly, when I think of some of the stuff she wears...
The fabric is as tough as old boots and wonderfully warm - much more so than corduroy. I've also got a pair of goose-shit green moleskin breeks which are perfect when you're out in the cuds.
