After market chain guards for triple rings

Blackspire make some big ring protectors designed for extreme MTB use, but I guess they might fit the bill for you too.

It will be an expensive option, though.

If you don't care much about your crank (commuting isn't going to be stressful enough to make much of a difference) maybe you could use a low-end crank from a recreational MTB, that includes the plastic ring? (Or maybe take the plastic ring from one and put it on yours?)

Or, Plan C: tuck the bottom of your pants into your socks while riding, so they don't touch the drivetrain.

Take an old tube sock, cut off the toe, and slip it over your leg - do both legs for the heck of it!

I like the tube sock idea. However, thinking of using a material that doesn't soak up grease which would make washing it easier

You could try going to a camping/backpacking store and get some Gaiters. They're usually waterproof nylon and used to keep snow and rocks from getting inside your boots.

Try this, works good, and cheap...

Why limit yourself to just the distance to work and back? Is two miles worth the effort? Why not find a route that will loop through some parks and make it six miles? I live 1 1/2 miles from the office. If the weather is bad I walk but, the idea is to spend time cycling each day so I ride six miles each way. That's the beauty of living close to work, options. See how many different routes you can come up with.
