Straps

This isn't necessarily about a leica camera but I need a good (preferably leather) strap for my m2 and a future m240 (fingers crossed).

Every recommendation is welcome.

Additional info: I'm in the EU. The simpler the design the better. I'd like to avoid adjustable ones, or the ones with neck pads. I prefer to wear the strap across my torso (instead of on one shoulder) and given that im very tall, I need about 57 inch (145cm).

If this is something too unrelated for this sub and I shouldn't be posting this please let me know. Thanks everyone.
