ULA Catalyst, older version. It’s a medium frame, J-straps, with either a small or medium hipbelt. It has around 500 miles on it with plenty of life left in it. Comes with hand loops, water bottle holders, hydration sleeve, and stash pocket (all of which they now charge around $50 extra for).
There are two tears in the side pockets stitched up very tightly. The repairs will probably last the lifetime of the pack.
Weighs around 48 oz on my scale.
