Staying in the Action
The whole point of a vest like this is keeping your kit on your body and out of your way, and the Exposure 10L actually delivers on that. Every pocket sits right where you'd expect it to be, so you're not thinking about gear, you're thinking about the shot.
When I'm photographing runners, I need to keep up. That means sprinting to the next position, hanging out of a Jeep, or running full stride alongside a subject with a full kit on. I can't stop to dig through a bag. With this vest, I can grab an extra roll of film, swap a battery, or pull a filter with one hand, without breaking stride or missing the moment. (And yes, I see what Moment did there.)
I've lost too many shots fumbling through some labyrinthian case trying to fish out an ND filter. That doesn't happen with this vest.
Having the vest gives me the assurance that I know exactly where everything is without having to take myself out of the moment. I get to be completely streamlined and avoid fumbling for batteries or filters because I know which pocket they're in and where, no need to take my eyes away from shooting to get into a backpack.
