The ULA Catalyst is the tried and true workhorse of the ULA pack line. No matter where the adventure takes you, the Catalyst is 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 UltraStretch™ 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.
Combination ice axe/trekking pole loops come standard; the weather is unpredictable, and we believe your pack should be able to adapt as fast as you can. Low-profile loops at the top and bottom of these packs accommodate removable top and bottom straps. Choose between a sngle top strap, or a Y-strap. Optionally, you can add an ultra-light bottom strap kit and be able to instantly add the capacity to strap larger items (tent, food storage, or sleeping pads) to the bottom of your pack as your gear needs change.
Weighing only 44.4 oz, this pack will lighten you up but still handle the toughest duties.
The Catalyst is a tough and light pack built for traditional backpackers.
Note: The Black packs do not include a Y-style top compression strap.
Note: Unlike ULA's website which includes both a "J" and "S" shoulder strap option, the Catalysts ranged in Ultralight Gear only feature "J" style shoulder straps. These are not interchangeable, unlike the hipbelts which are and are not sewn in.
Note: Actual colours may differ slightly from reference pictures (Different panels, different buckles etc.) Side pockets on the green pack are black instead of green.
TIP: If you are on the outer edge of a hipbelt size, order the larger size. [ Ex: If you are 38", you will notice 38" is the last number of the Medium Hipbelt and the first number of the Large Hipbelt. You would want to order a Large.]
TIP: If you're between torso 2 sizes, order the smaller size.
