Say hello to the Ultra Catalyst; the same Catalyst you know and love, only stronger and lighter than ever. Purposefully constructed of Ultra 400 in high abrasion areas and Ultra 200 in low abrasion areas, we’ve selected a fabric matrix that maximizes durability while keeping the pack ultralight! At only 40.1 ounces, it’s a full 5.3 ounces lighter than a Robic Catalyst!* (* Based on a medium torso w/ medium hipbelt.)

In our commitment to making quality, durable backpacks that last a lifetime, we’ve been hesitant to build packs out of many popular ultralight fabrics. Why Ultra? 15x stronger than steel by weight, twice as abrasion resistant as standard 420D nylon, and waterproof to 200 psi, we’ve finally found an ultralight fabric that matches our high standards. Front pocket is ULTRA StretchMesh for added abrasion resistance. Note that to maximize water resistance of the ULTRA Catalyst, these packs do not have bladder hose ports.
The Ultra Catalyst was built to carry loads of up to 40 pounds; it will haul a bear canister horizontally or fit your fishing, climbing, or photo gear. An internal frame with a twin stay framesheet, comfy padded hipbelt, and contoured shoulder straps make for all-day comfort even when loaded down. Front mesh pocket, dual hipbelt pockets, and Ultra 400 adjustable side pockets make it easy to stay organized whether you’re on a thru or just out for the weekend. It can even be checked as baggage on a plane! No wonder the Catalyst has consistently been among the top 5 most popular packs on the Pacific Crest and Appalachian Trails!
