quick release belts available here: http://www.worcestershireleathercompany.com/categories/Quick-Release-Leather-Belts/
Not sure if worcestershire leather co. makes them for EG but they seem like they are exactly the same to me.
Thanks for the mention evrybody and to clarify any confusion, I designed, developed and produced the now much copied Quick Release belt back in the nineties when my company supplied the first ones ever to EG/Needles/Nepenthes, Denime and loads of others.
Since then I now only make for the end user as I find supplying shops tedious. My former colleague and friend Martin F looks after the stores these days while I do bespoke individual work only using only British materials making by hand here in England. The same belt, leather, buckle and hand stitching but I don't do white as I only use 'real' bridle leather.
Hope this helps,
