I ride with my vintage Frostline Kit saddlebags most days. Here they are on yesterday's ride on my Raleigh Sports. They have faded a bit over the years.
I now attach them with cable ties to the rack and leave them on so I'm always ready to ride with stuff (toolkit, water bottle, coffee thermos, extra clothes) and to get stuff (groceries).
Sewn by my mother-in-law as a gift to me in 1983 or so.
