I've had this bag now for about three months and I use it most days, carrying items needed when I'm out walking my dog. Nothing critical, thank goodness (well, dog treats, poo bags, my house keys and my mobile phone?).
The bag itself is very good, being made of unbelievably soft leather it is very comfortable to wear.
Frankly, the belt doesn't adjust small enough (and I have a 36inch waist) so it constantly tries to slip down over my 'hips', and the clip that holds the thing together round your waist is pretty useless. At the least provocation the clip releases, allowing the entire contraption to fall to the ground (or into a stream if you happen to be crossing one at the time - don't laugh, it happened). Bend, to pick something up off the ground (a ball to throw for my dog, for instance), there's a faint click and the belt suddenly feels loose, you stand upright and the belt falls.
If anyone can suggest a modification to allow me to make the belt shorter and the clip more secure I would be very interested to hear.
