My favorite pack of the last 60 years. August 13, 2017
Reviewer: Barry Wohl from Sheridan, WY United States  
I've been backpacking since 1957, and I've owned: Kelty A4 external frame, Gregory Wind River, Monolite, Ospray, Kelty Cloud 65, AND MANY MORE.  For 15 to 35 lb, my Catalyst feels the best on my back.  I've used it on about 20 trips from 2 to 8 nights over the last four hiking seasons.  I'm no longer looking for anything better.  Along the way, my other equipment has gotten lighter and smaller, so I have extra space in my Catalyst.  AND I got to upgrade my waist belt to one size smaller as I shrunk too.  Happy days.

JMT Thru-Hike March 12, 2017
Reviewer: Todd from Longmont, CO United States  
I was fortunate enough to snag one of these packs when it was offered in Cuben Fiber. What an awesome pack! It easily and comfortably handled my JMT thru-hike last summer, including carrying my Bearikade Weekender. Very comfortable, and tough. Highly recommended.

Excellent Pack! January 8, 2017
Reviewer: Mark Weidinger from Prather, CA United States  
Excellent, high value pack at a good price. Coming from running 55+ lb loads in my faithful Dana Alpine, I was concerned about the suspension system and load comfort, but it worked fantastically on 7 day Sierra trip starting with 42 total lbs. and dropping as food and fuel (and bourbon) was depleted. Seems like this pack’s sweet spot is about 25-30lbs.  

Everything about this pack has been so well thought out, from how it packs and rides, the storage options, and accessing your gear. It’s also a sweet looking pack with more volume than I will likely ever need. I got the large with large belt and regular straps, run a Zpacks Cuben dry bag as a liner (2oz), dropped the hand straps and bladder pocket. Fyi I’m 56yrs, 6ft, 215lbs with longer torso.

After 40 years of backpacking I’m finally lightening up, and can’t endorse this pack and ULA gear enough. Thanks ULA!

Versatile and Comfortable Pack September 2, 2016
Reviewer: Axel W from Duvall, WA United States  
I have used the pack for a number of different trips, but recently took the pack on a  7 mile hike with 2300 vertical feet with a full 40 lbs of gear (well, probably 45 lbs) with a 500 ft climb over 200 yards in the middle and a corresponding climb back down the next day.  The Catalyst worked great even with a full load +!  The hip belt kept the weight off of my shoulders, which allowed me to climb over and under logs, grab roots on the way up, and keep my balance on the way down.  Thanks ULA for making a great pack that works with 40 pounds or 20 pounds of gear!  PNW fan!

First trip, pack worked great August 21, 2016
Reviewer: David Marshall from Oregon, United States  
I finally took the break in trip with my new Catalyst.  The trip was not long, but gained 2400 ft in 4 miles with the end result being beautiful Maxwell lake in the Eagle Cap Wilderness.  

The pack performed very well with a trail weight of 28 pounds.  In the past, I've had to tinker with my packs to dial them in over multiple trips.  After following the YouTube set up and fitting videos, the pack fit and worked like a charm.

While I'll keep chipping away my pack's trail weight, the Catalyst is flexible enough to go both lighter and a bit heavier for early summer Cascade volcano climbs.

The Catalyst is a great combination of light weight and versatility.
