While I like the idea of waterproof breathable I have come to think that nothing works like we wish it would. As long as the material is wet on the outside there does not seem to be sufficient reason for the moisture vapor to move through the fabric. That leaves pit zips and similar dodges but all the time we are venting in damp air. At best what we get with breathable fabrics is faster drying after the rain.
Free advice worth what you paid for it. ;-)
