This is a thread just to answer some basic questions such as frame size and changes and anything else.
Yes, we have made a lot of small changes over time. Almost all of these has been to provide a better overall product to customers, though sometimes a customer may have preferred how we did it previously for one reason or another or perhaps just familiarity.
Example:
Frame changes. We currently use a smaller diameter frame than we started with. The frame is not as stiff as the original, but in general the frame fits people better, and can still handle 200 lb plus loads. Simply put the other one was overkill without much of a need. Was it more durable ? Unlikely, there has not been any issues with the slightly smaller diameter frame. In essence, save a little weight, fit people a bit better
Hipbelt Dual Buckle: This is about fit, ease of repair in remote places and ability to change tension a bit if needed. Yes, some prefer the single buckle mechanical advantage, however in our testing never was the extra tension actually needed to secure the belt. Yes, in a lot of other packs, the tension is required, but not so much with our belt system. For many people, the ability to change top and bottom tension allows it to fit better and be worn in a more traditional area.
This is just an example of a couple changes. If you have other ones that you would like a more thorough explanation just let us know.
Thanks
