As I do not like stuff around my neck, I have DIYed this setup:
Here the camera cannot slip off my wrist when I let go. The small loop on the left side comes in handy when I want to move the weight for to the other hand quickly & for a short time or as a support when holding it in both hands.
The ends of the straps have been "T-shaped" using a hot air gun to melt the plastic fibers into shape, so the strap cannot slip through the fasteners.
I love this arrangement, not only during hiking.
Cheers from Berlin!

P.S. Never mind the lens in that picture :-)
