In reply to Steve Perry:
Hi, I've got some enduro trousers too. If its cold they're absolutely brilliant. The reinforcement isn't super sturdy looking but mine are holding up fairly well after three winters and a lot of use. Theres a bit of scuffing on the thigh but pretty unmarked elswhere save for the integrated gaiters which have a few holes from crampon strap rubbing...they still work fine tho.
If its mild...ie above freezing you'll get sweaty and they're not great if you're working hard and it's raining. They are however fantastic in cold, great mobility and a nice cut...at least on me. Only thing i'd change is a proper bib and sell them with braces...they don't stay on me without.
hope this is of some use.
