The middle-sized option in the Mystery Ranch Catalyst line, the Catalyst 22 Backpack is an everyday pack with a tough-but-eco-friendly build. The Cordura re/cor exterior is highly abrasion-resistant and made from recycled plastic bottles to reduce waste and our use of virgin materials. We like the unique 3-Zip construction that lets us open the front panel completely for easy access to everything in our pack from the bottom to the top. The Catalyst 22 features side water bottle pockets, a pocket that fits laptops up to 16 inches, and zippered organizational pockets to keep our small packables safe and organized for our day trips.
