Ok, so my next project is a new backpack. Never done it before. Its going to be used for backcountry skiing and mountaineering, so it dosent fall into the ultra light category since it will need to hold quite a bit of weight.
For those who have made packs with "structure" what kind of padding have you used for the back. I was thinking of using a strong mesh, then foam, then the pack material. I know I know... real men just use clothing, efficient packing and their ground pad for back comfort.. well I'll likely be wearing all my clothes when using this pack or may not be doing an overnighter so I'm not going that route.
Next I'm looking for frame sheet ideas, derlon rods? lite plastic sheets? I'm open to ides, and then where do you buy them?
