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 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. ULA has replaced the regular mesh front pocket with an UltraStretch™ mesh for added abrasion resistance and durability. Combination ice axe/trekking pole loops are now a standard feature; the weather is unpredictable, and we believe your pack should be able to adapt as fast as you can. We've also added low-profile loops to the top and bottom of these packs to accommodate removable top Y-strap and/or bottom straps. Bottom Line? The Catalyst is a tough and light pack built for traditional backpackers. Pack Weight TOTAL WEIGHT: 1.324kg* Listed weight is for a size medium torso with size medium hip belt.
