I usually were regular jeans for my work commute. They are comfortable to ride in and from the motorcycle wrecks I've responded to (I'm a paramedic) that happened at city speeds, they seem to provide adequate protection. I know a few of the guys here will tell you they get all suited up to go 1 mile to buy milk, and that's fine if you want to spend more time getting ready and disrobing than the actual task takes to perform. But to each his own. If you really believe you want something a bit more substantial that's not leather, check out Icon's line of Steel Jeans. I've got a pair that I wear when I'm going on a ride through the mountains and don't plan on dragging knee or pushing it too hard. They are relatively comfortable and offer a greater degree of protection than standard jeans. But if that's the route you choose, Id get a pair that is one or two sizes larger than what your actual waist line is because they add in the Kevlar and reinforcement after the jean is manufactured, so the sizes aren't exact. Plus it's nice to have some space so they're not squishing your guts when you lean over the tank.
