Fez,
With regards to pouches that stay open.
I now use the ones produced by Unger, but I used to have them made up specially when I first started as no major Manufacturer made pouches.
But I designed ones that had pleated sides, this way you did not need wide pouches or ones that were as high as you had much greater depth.
The ones I made myself were far more comfortable in use.
Being as they could hang open a lot further, we also had a popper fastened flap for security, which could also be tucked flat inside your pouch while working.
Anyway, just thought I would say that they can be made! Have even thought of writing to unger myself as I find the ones they make so frustrating.
Wish the guy that made them up for was still in business as I reckon he could have had a potential sideline selling to the likes of us.....
regards,
Ian
