Q -1. why no frameless pack?
A -1. I don't like a frameless pack if I expect to carry more than a few pounds or if I am on a long hike. I also don't like anything that complety lays against my back. For a hike of a day or two it is OK, for more than that I want some ventilation. Remember I am old.
Q -2. what happened to the external frame pack idea?
A -2. This frame will be a sort of hybrid if it works like I hope. Have you had a chance to look at one of the Exodus Packs in person? The Exodus are made in two parts, the stand alone frame and the pack bag. I lot of really good ideas but heavy.
Q -3. Whatever, I cant wait to see this project, an 8-9oz pack with a titanium frame.Amazing
A -3. I have a Titanium/Carbon Fiber Frame (9oz-) that my Cuben Pack (2.10oz) and my G6 (3.4oz) attach to.
If it works out the frame should be over-kill up to say 15 pounds but very good up to 30 + pounds. This is really where I am going with the idea and the hoped for light weight. Think Summit pack or winter pack where you need more pack volumn.
