well the opportunity arosed once again, but this time i went prepared with the Domke backpack strap, and am not kidding, 5 days of an average of over 12 hrs of constant walking each day, no no no pain any where on my back or shoulders, but my toes are gone.:D:D:D
beauty of the back pack strap it can be slung as a shoulder strap or back pack strap in a milisec
So , by cahnce does Domke make different colour backpack straps
