8 different bags accumulated the first few years of photography. today I have no interest in bags.
commercial AW mf
photo trekker aw v1 and v2
magnum aw
min trekker aw
nova 3, 4, and 5
some waist packs like off trail etc
I use my photo trekker aw v1 for over 20 years now for weddings. I always lubricate the zipper. its been around the world and it been through heavy rain, even without the aw cover. no other bag comes close to it.
