This is actually my second 1 day specialist backpack. So now I can go for 2 days :)

More seriously, the first one was so good, it ended up being my permanent large camera bag for traveling with my DSLR and all the lenses and accessories. Plus it had room for canteens, the phone, a place for the sunglasses and so on.

But whenever I wanted to hit the beach or do a day hike without taking all the camera gear, I had to empty the out camera stuff and refill it with beach towels, or hiking stuff like rain gear, first aid kit, food etc.

That was inconvenient and vacations are all about convenience. So for day tripping and short hikes I decided to get another one.
