The largest member of Kelty’s versatile Catalyst family of packs with innovative PerfectFIT suspension, the Catalyst 80 boasts a long list of features that maximize comfort and convenience for extended backpacking trips, including a removable 10L day pack.

The main advantage of the Catalyst 80 over other similar capacity packs is its PerfectFIT suspension system for accurate on-body size adjustment that allows you to customize your fit in seconds. With PerfectFIT, gone are the days of taking measurements and trying on various pack sizes in a gear shop to determine the best fit for your particular body (or ordering a pack online that may or may not fit once you’ve received it). In just three steps, you can easily find your fit in the Catalyst 80: just loosen all the straps before putting the pack on; next, tighten the waist belt and shoulder straps once you’re wearing the pack; lastly, locate the FIT straps near your lower back and pull downward until you achieve optimal comfort. The Catalyst 80 with PerfectFIT will accommodate backpackers with torso lengths between 15.5 and 21 inches.

Also featured in the suspension of the Catalyst 80 are dual hollow aluminum stays and an HDPE framesheet. The waistbelt is HDPE reinforced and offers two layers of padding, as do the shoulder straps. Load lifter straps relieve stress on your shoulders and an adjustable sternum strap positions the shoulder straps across the chest to prevent chafing under the arms and on the shoulders. Side compression straps secure the contents of the Catalyst 80 for optimal balance and load distribution. An integrated spindrift collar and a floating top lid allow you to carry even more gear and further aid in securing the Catalyst 80's contents.

The top-loading Catalyst 80 features a unique side-access sleeping bag compartment that makes it easier to access other gear without having to unfurl your bag, or gives easy access to your bag without having to move other gear around. Another great organizational feature in the Catalyst 80 is the detachable front clothing compartment, which can be completely removed and used as a 10L day pack for fast and light travel on shorter trips. Additional features include stretch mesh belt pockets and water bottle pockets, a zippered side pocket, ice axe/trekking pole loops and a key fob. A lined interior pocket and built-in tube exit make the Catalyst 80 hydration compatible, as well.

Thanks to its PerfectFIT suspension, the Kelty Catalyst 80 is one size fits all and provides for an optimal carry weight of between 25 and 55 pounds.
