Catalyst

The ULA Catalyst remains the tried and true workhorse of the ULA pack line. No matter where the adventure takes you, the Catalyst will be there - ready to carry loads of up to 40 pounds. If you're looking for a pack that will haul a bear canister horizontally or carry your fishing, climbing, or photo gear with ease, the Catalyst is an excellent choice. Not only will it hold a good-sized load, but it can also be checked as baggage on a plane! The ULA Catalyst has consistently been among the top 5 most popular packs on the Pacific Crest and Appalachian Trails. Internal frame with a twin stay framesheet, comfy padded hipbelt, and contoured shoulder straps make for all-day comfort even when you're loaded down. Front mesh pocket, dual hipbelt pockets, and Robic adjustable side pockets make it easy to stay organized whether you're on a thru or just out for the weekend. Weighing only 44.4 oz, this pack will lighten you up but still handle the toughest duties. Bottom Line? The Catalyst is a tough and light pack built for traditional backpackers.
