Think Tank Sling-O-Matic 20 Backpack - Changes Shoulders and Holds Pro Gear Plus

Think Tank Photo introduces the Sling-O-Matic, the photo industry's first sling bag that can be easily switched back and forth to either shoulder. The Sling-O-Matic's adjustable, fully padded shoulder strap "automatically" slides along a set of rails to change which shoulder the bag can be worn on. This is the innovative solution to the problem inherent with other sling bags: only being designed to wear the sling bag over the same shoulder.

With one smooth motion, the Sling-O-Matic can be quickly switched to the opposite shoulder without losing the characteristics that have made sling bags popular among photographers. The Sling-O-Matic series offers three unique bags to choose from, depending on the set of photo gear a photographer needs to carry.
