I am going to be spending more time in cold and wet conditions and since most membranes and laminates wet out within a day I was thinking of just making some items using fabrics that are just naturally inherently waterproof so that I did not have to worry about reapplying DWR or keeping them clean just so they breath.
What I am looking for would include pit zips, a full zip, a hood, and be durable. The weight is not really a concern for me as long as I can keep it to around 10oz or less.
I have looked at the Packa but I do not need the extra area for the pack and I have looked at the one from antigravitygear.com but I do need pit zips and I believe that it is not that durable.
As far as I know there is the cuben fiber stuff and the silnylon stuff. Since I don't care about the weight I don't need the cuben stuff. For silnylon should I be looking at stuff like the Cordura or is there anything else out there that I should be leaning to? Thanks.
