Critique My Pack Idea

I think I get the concept. It is a little hard for an old guy like me to follow the drawings, but is the top compartment the trapezoidal shaped part? Will it be able to scissor up and down to accomodate diff stuff sacks?
Cant wait to see the final product.

keep thinking outside the box.

You know, I hadn't thought of that. But, when you look at the design as it is…its already designed in such a way that you could rig that in seconds. By simply running the anterior attachment cords for the upper lid compartment down to where the bottom compartment wrap-wall attaches to the main compartment front panel you create the proper anchor point and then the whole top of the pack slides down and compresses without effort. But that might mess up how the load-lifter mechanism works, as it uses the higher position of the upper lid compartment for mechanical advantage to lift the bottom section up.

But, I love that such a suggestion was immediately implementable by the current design features (despite being fairly minimal). One of the things I did with this was trying to make each design feature do double-duty whenever possible. Just like gear, each feature needed to satisfy mutliple needs/uses.

Thanks for that idea, it helps me tighten up my design where ever mental weakness still exists in the design.

The ideas and help that you get is great.

You had mentioned using tent poles for rigidity. why not rig them in a sleeve and they could be your load lifters , thus freeing your top lid to be part of the compression mechanism. In this case you could vary what you carry in the middle. (sorry,but my mind is still infuenced by my modular pack that I just made)

enjoy

P.S. check out Daryl"s pack – he uses a u channel made out of alum or carbon fiber to transfer weight to the hip belt

John,
Great Cad drawings of the pack I wish I had that talent, I still rely on my hand drawn drafting skills.
The design is pretty cool the internal compression was used on older heavier packs of Yak paks,Dana designs, Vortex packs in different ways of configuring straps. The pack looks like a very progressive design and very cool.

From the drawings the pack looks to be about 8 to 10 inches deep. The pad in the sleeve frame should not be on the outside of the pack or it will push the load away from your back put stress on your shoulders pulling away from your back. The pad should be in a zippered pocket that needs to go inside the pack and half of 3/4 lenght pad thickness goes inside the pack and the other part stick through 3d foam or nylon. You need to make the pack back 11.75" wide at the stitch line to allow the Z rest pad virtual frame to work correctly 20 " tall.
