If you plan on getting into this and want variety, some dark green parachute cord would look stealthier.
Yeah, I was going to suggest paracord. It's not hard to weave it into a good strap: http://www.tacticalintelligence.net/blog/slatts-rescue-belt.htm or http://chubbysurvivalist.com/2009/07/31/braided-survival-belt-with-550-mil-spec-paracord/ would serve as a base pretty well.
The strap here is sort of the Home Depot Artist & Artisan silk cord strap, but the huge knots at the camera make it look like it'll get in the way...
