Chris is the new kid in town, but his workmanship is as good as any I've seen and I have or have had all the packs from the other guys, MLD,ULA,GG.
I already have one pack from Chris currently and I going for a 2nd pack in the near future. He is one of the few, that will custom make a pack per your specs. One thing I feel many lightweight packs lack is a mesh lumbar pad, to help the pack stick to your back.
So, I had Chris sew an 8" tall section of mesh the full width of the lumbar or bottom section of the packs back-panel. I love it!
The pack came in at 2 lbs which ain't too bad for a pack that's made entirely from X-Pac, and Dyneema X fabric.(no wimpy mesh) The true test will be over time, as to how well the stress area seams hold up(shoulder straps and hip-belt wings) But I'm confident that his stuff will hold up with the best of them.
