+1 for the Sun Sniper sling strap with the activity clip that attaches to your belt or the waist of your pants. It has an elastic strap which is easily manipulated with one hand while not needing to see it also (after a little practice!).
The strap does use the tripod attachment, but just get a Joby Ultraplate for the bottom of your camera. It is thin, Arca-swiss compatible and has an attachment hole for the strap. So you can attach it to a tripod with the strap still attached.
I've been using this setup for almost 4 years with no problems.
