Alpinelight wrote a review of Patagonia Rubicon Pant - Men's on March 8, 2012
I have 100+ days on my Rubicon pants - about 75% resort and 25% backcountry.
Close to half of those days are storm / powder days. Somebody asked if these are waterproof. Yes, they are fully waterproof in wet Tahoe conditions.
They're just roomy enough to not make me look like an adventure racing weirdo when I hit the park, but no problems when skinning in the backcountry on a splitboard.
Definitely heavier than typical backcountry gear, but they vent very well and I tend to prefer burly over superlight. Adventure racers will hate them.
I routinely fall on rails, bushwhack through thorn bushes, scratching my way through narrow gaps between trees, throw the pants in a bag where they rub up on sharp board edges. Nothing seems to have damaged them. I expect them to be indestructible for another 100 days at least.
Only issue is that the Patagonia label eventually fell off.
