ULA Circuit and ULA Catalyst for sale, both small with small hip belts. The Circuit has been used for about 600 miles and the Catalyst has been used for 1300 miles. This might sound like a lot of miles, but I take very good care of my gear because I want it to last as long as possible. Both packs are in very good condition. I'm pretty sure I have the mesh pocket and water bladder pocket for both. $160 shipped for the Circuit. $160 shipped for the Catalyst. I'll post pictures as soon as get these bad boys washed and dried! I love both of these packs, but I want to upgrade to a cuben fiber pack.
