The new harnesses have been shipping for a few weeks. It is the same harness conceptually, just some change to finish details , range of sternum adjustment etc and cut a bit wider. There are no core changes to suspension, just some minor changes to the offering (for instance PALS is standard on hip belts now instead of an upgrade, frame extensions included with an opt out as well).
We are also going to be offering some custom pack bag options. Although, we really like and prefer the efficiency of our pack bags and the water proof materials we use, we will offer some options and alternate materials , or styling as a custom shop (Dyneema, Cordura etc). For instance if you want two long pockets instead of water bottle pockets , then it will be a custom shop. The custom shop stuff will have longer lead times and be a custom quote.
