So, I have never been satisfied with GORE TEX head gear (your mileage may vary), so I have been searching for a local Portland made product OTTER WAX with no luck, so, I defaulted to good old, Peoples Republic of Seattle, Filson Oil Finish Wax. After working into the seams and surface and hitting with a hair dryer on HIGH, first test was great. Not noisy, after a one hour in the rain walk, minimal inside moisture, mainly on the rear main vertical seam. After a second coat, with obvious extra attention to all seams, I am satisfied with the results. Now on to the flashlight reflection tests in darkness. If anyone owning a GEN III Night Vision Device tries this, please post the results?
