A neat way to keep your items safe and secure especially when traveling. Pocket Socks or Travel Passport Security Socks comes with a built-in zippered moisture-resistant security pocket for holding Passport, ID, Key, Cash, Credit Cards, etc. One zippered pocket per pair secures and conceals valuables with its industry-leading zipper. The zipper won’t set-off airport metal detectors, but do remember to remove pocket contents before the screening. Happy Traveling!
