RE: Rivers West
Nothing but good to say about them and their customer service. One thing people don't realize is that these things are waterPROOF, not waterRESISTANT. For something to be truely waterproof it can't be a permiable/breathable membrane. That means that it keeps water out and it keeps water in equally well. You can't expect to put these on and do heavy exertion in humid conditions without getting wet from sweat. Their newer LAW series addresses the problem pretty well with vents but the same issue still applies.
One of my friend's was leaking around the seams. One call to customer service had it fixed; they told him to wash it. Sure enough, one cycle through wash and dry and the seams sealed up and never leaked again.
