Do you mean hand strap or wrist strap? The two posters before me have interpreted it both ways.
I have this hand strap which is good although I don't use it much these days.............
edit - looked for it but couldn't find it.
It's a black leather one with red stitching made by 'Herringbone'
Very very similar to this...............

I've had it various DSLR bodies up to 1D mk iv sized.
Looks like the sort of thing but they don't have any pics of it on the camera - does it look similar to this when in use?
But the OP has made it clear he doesn't want a wrist strap.http://www.wexphotographic.com/buy-...duct=1531291&gclid=cnfqsyeqwtacfbgy0wodjj4cbg
Honestly, comfy as a comfy thing, can be purchased from other retailers too of course
