Flydad,
I have recently had a similar experience with Cloudveil. I bought mine on sale at Up Country which is a great fly shop on the Farmington. My 8x pro waders were leaking in the seam near the left knee. Cloudveil was redesigning their gortex waders for 2008. It cost 23.00 dollars to ship them Fed X but within 3 weeks I had a new pair of the 2008 version at my door step. I too am disappointed that they leaked right away and worry about the new pair. However I concur with you on the great warranty service. I might add that I just retired my Hodgman neopreme waders after 5 years of reliable service! I hope going high tech was a good choice. They sure are comfortable. We'll see.
