I’ve been an amateur photographer for over a decade now, and in recent years my collection of gear has grown a lot. Back in 2008 I was planning a trip to Europe and needed to get a good camera bag that could handle my dSLR, lenses, my laptop and various bits and bobs. Recommendations from friends led me to the Lowepro Fastpack series. They hold a ton of stuff, and have a unique side-loading system for your camera. It allows you to keep the backpack on one shoulder and swing it around to get your camera out without having to put it down.
I bought the 250 model, and fell in love with it. It traveled all over the world with me for the last four years: Europe, Mexico, Burning Man and more. It’s extremely light when unloaded and roomy enough to hold a massive amount of gear when full. The laptop sleeve and camera chamber both have enough padding that my camera, lenses and laptop have survived a few terrifying falls when the bag was knocked off to tables, cars, etc.
Recently the plastic logo on the shoulder strap came apart, leaving a hole in the shoulder strap. I emailed them asking about it, since their website says they have a lifetime warranty. They asked me to send them a photo of the damage, then shipped me a brand new one without having to send back the old one. Awesome customer service!
List price is $129, but it sells on Amazon for less. I was hesitant to spend that much on a camera bag, but after seeing $5000 worth of gear come out of it unscathed after a nasty fall on to a concrete floor, I am glad I did.
