Did my research & settled on Marsupial Gear a couple of years ago. Had one of their binocular carriers (not the enclosed one) for 2 ish years. It hasn’t been hammered but has been in weekly use since, I’m really impressed with their kit. I would buy another if this one ever gets lost (why would it?) or destroyed/ broken beyond repair.
If you bide your time, they do have sales on with old camo patterns with 10-15% off.
Postage to the UK was no issue, it’s an option at checkout & took 2 weeks I think, maybe slightly longer.
