Back in the 80s I was shooting a lot of tennis and noticed a guy from OS using an Adidas Camera bag. I just had to get my hands on one - and I did, special order through my local Athlete's Foot store. Wasn't cheap for the time, but it was a great bag and you'd *never* suspect it held camera gear (unless you picked it up!!).
Still have it, although it hasn't been used in a quite a while; basic dividers and 3 pockets - but the leather trim and 3-stripes are certainly not Lowepro branding standard.
