i was up near seattle and found these pants called "key". i didn't expect too much from them, but they've been great for riding. they were clearly work pants cause they came with suspender rivets (which i removed). i have some levis and i definately prefer the key pants. the cut is slightly more narrow and better for riding. also i carry a u-lock in my back pocket. on the levi's i got a hole through the ass but on the keys theres a hole on the pocket. so something about the cut is obviously a step up.
i agree- patching is the best route for a worn ass.
