I really like organizers. Small ones, big ones, I like them all. One thing I have come to realize about organizers is that there is never a single one that can suit every need. The things you carry dictate which layout needs you might have. Thus, when I find a pouch that has a unique or interesting layout, I usually buy it.
The Kifaru Tombstone organizer is quite unusual. Instead of the regular clamshell and zipper, this one is a trifold with hook & loop. It is 6"x6" and can accommodate a wide range of gear. I have set one up here as a mobile office kit and another as a tool kit which goes to show how versatile the Tombstone Organizer is. It can also hang inside a bag or pouch with loop lining. These run $12, and although Kifaru charges a minimum of $10 to ship, they represent an outstanding value for a piece of US made gear.
Check them from out Kifaru here.
May your bags be well ordered!
