How to minimize wear on pants I commute on bike and I wear jeans (which I work in).  I find that after about 500 miles of bike commuting in a single pair of jeans I've got holes in my pants from the saddle-jean rubbing.

My problem is probably accelerated by the fact that I have a fabric seat, the "Jamis Aurora Sport" saddle which comes stock with the Jamis Aurora.  However, I'm told that people experience similar issues with non-fabric seats.

Having said that, I'm trying to figure out whether I should get a new saddle (something smoother like leather or plastic), or alternatively wear a pair of athletic shorts over my jeans (easily/quickly removeable at work/ in public).  

At my current rate I will need to replace and/or repair a pair of jeans every 2 months.

My question is, what measures can be taken to minimize the rate at which my pants wear through when commuting (without the obvious solution of having dedicated pants for cycling)?
The obvious answer would be to get some Cycling Jeans, i.e. jeans specifically designed for cycling in. These have reinforcement and stretch in the right places and often have other features such as deep pockets, a loop to carry a small lock and reflective strips.

Levi, Rapha, Muxu and Swrve all make cycling jeans, so there's a fair amount of choice.
