In reply to Billie Goat: I've got some of the prototype ones but I assume they're pretty similar to the new ones....
Bombproof (and seemingly quite gabbro proof as well), pretty breathable, excellent mobility and easy to climb in. The only shortcoming is that the velcro bit at the ankles could be a bit longer to make putting them over big boots and gaiters easier. Comfy when wearing a harness as well.
