The 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 18kg. If you are looking for a pack that will haul a bear canister, or carry your fishing, climbing or photo gear with ease, the Catalyst is an excellent choice. Not only will it carry a good sized load, but it can also be checked as baggage on a plane! The Catalyst has consistently been among the top 5 most popular packs on the Pacific Crest Trails and the Appalachian Trail.
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 50 oz – including all the extras! – 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.
