I could agree with that, I am only pointing out that at times it becomes absurd focusing on mvtr ratings that measure microscopic pores when you have an eight inch zipper that you can open up. Especially when you realize that Patagonia sent the same piece of fabric to 6 different companies and got six different results. They even sent the same piece of fabric back to the same company and received a different result. Everyone shouldn't hang their hats on an mvtr rating.pit zips are great and i dont buy items without them but they arent the end all be all.
