SealLine Urban Backpack Organizer
The organizer is 10" wide by 10-5/8" high. According to the instructions, its meant to slide over the stiffener that is part of the SealLine Urban backpack. It doesn't have any structure of its own so it needs to be slid over or hung from something.
It has four pen/pencil pockets, one of which is just big enough to hold a 2 AA cell mini Mag light. The other three are slightly smaller. There are a 4" wide by 5-1/4" deep slip pocket, a 5-5/8" wide by 6-1/2" deep zippered mesh pocket and a 10" wide by 6-3/4" deep slip pocket.
Sewn to the top of the largest pocket is an 18" long non-detachable strap with a clip on the end.
All the pockets are on one side of the organizer.
There's a 1" loop on the top.
Its made of light weight nylon/polyester. Nicely made, but not as robust as the Tom Bihn products.
Eagle Creek used to make two types of organizers, one mostly file folders and the other mostly pockets, similar to the horizontal Freudian Slip. They are both 13" wide by 9-1/2" high and occasionally appear on ebay and similar places.
