Good camera strap for Nikon D3100?

I would like to invest in a solid camera strap for my Nikon D3100 that will be long enough to strap across my chest. (To avoid worrying about pickpockets when shooting in large cities.) The stock strap that came with the camera just isn't doing the job for me. Any suggestions would be greatly appreciated.

I have always used the strap that come with my Nikon camera. I have NEVER had one fail.

I have NEVER had a pickpocket or any other thief attempt to steal my gear.

See if binocular chest harnesses work out.

With the kit 18-55 lens, this just might work out.
