My big question in life:
Why aren't all backpacks water-proof?
My smaller 'daypack' that I took to india isn't water proof. That didn't matter in India, as I was in the dry season.
But now I use that bag to carry my textbooks and notes and sometimes laptop about in london. The other day I was caught in a massive flash storm whilst on a walking research trip. My notebook, inside my backpack and has plastic covers still got damaged by water.
My big backpack is for sure not waterproof. Why? Why do backpack makers insist I provide my own lining inside or out? Why don't they use some non-expensive version of gore--tex in there?
Hi Andy, I can only hope you and Rodney can finalize the design and construction of your Hobo Traveler Bag.
I met Rodney through a lightweight backpacking site. A couple of emails and he made an excellent lightweight bag to my specifications. I was surprised at the excellent workmanship, fit and finish. The bag has performed beautifully on several canoe trips through Canada.
Best Holiday wishes to all who read Hobo Traveler.

Ash, this is truly a great question.
Why aren't all backpacks waterproof?
I do not know the answer, my first guess is because all the manufacturer are following the long held types of ideas. Canvas bag, then nylon, however only the scuba bags are waterproof.
I have an accidentaly almost waterproof or air tight pocket. I found my passport that was in it, inside the room started to mold.
My camera bag does not breath, I am going to make it waterproof and also allow air to enter and leave by way of mesh. The AC in the rooms is causing havoc, life was easier when I was on a cheaper budget. AC is a continual problem, and nice, but difficult.
Condensation I think this need continually researched and explored.
I have a waterproof backpack cover, it totally repels water. The to me is not needed, if the bag is waterproof. I do believe though I also must somehow stop mildew, condensation and other moisture or humidity problems. I hope to engineer into the bags solutions.
I agree that breathing is important, especially for gadgets. This is why I think the 'gore-tex' style materials are ideal for backpacks... it is waterproof but breathable. My boots are gore-tex lined... I can walk in puddles and my feet stay dry. But also, my feet can breath, so they don't sweat then sit in pools of water like they could if it was just water-proof plastic.
Problem with real Gore-tex is that it is over-priced and gimmicy. My normal everyday shoes have a lining that is waterproof, breathable but much cheaper and not 'official gore-Tex'. Works fine.
Little mesh windows in the right places would also be a good solution. I maintain that I don't expect to be able to throw my backpack in a river and everything inside remain dry. If I was boating I would wrap it in a tarp. But being resistant to very heavy rainfall should be on the designer's mind.
