Hi Susan. Any time you see a "(number)K" rating for waterproofing it refers to the water column test. This fabric is rated to stop a 5000 mm water column over a 24 hour period of time. Any more than that and the fabric starts to leak. I highly suspect you've seen ratings of "10K" not "1K" as the latter seems ridiculously low. That just means the fabric will withstand a 10000 mm water column for 24 hours. Most fabric are in the 10-25 K rating. We're starting to see some 30K jackets out there and even the odd 40K, but they are not widespread yet. Gore-Tex does not use this type of testing to "rate" their fabrics so the waterproof rating of a Gore-Tex piece is "guaranteed". That means if it leaks, they will warranty it no questions asked.
