hey karl, seems like you 'da man when it comes to rain gear, but i am wondering why you don't use goretex. it is not the goretex fabric that wears out, its the water-proofing sprayed on the outer shell that wears off. it is a necessary part or of the system ~ for instance, heavy use or multiple washings with detergent will wear out the coating sooner. this allows water to permeate through the outer shell (usually nylon) and this inturn, allows water to "push" through the goretex, which IIRC, is waterproof to 8000m per inch sqaured, and breathable to 2000 microns per square inch.
Revivex is made by Gore ind., and used to re-apply the water proof coating. wool, IMHO, is great, but heavy and not even close to windproof. i have found that sweat cannot escape rubber or waxed gear, and it is impractical to change gear in the wet-wilds, when already wet from persperation. any thoughts?
