Hey, I was trying to find a new look for my Hunter about a Week ago, my plan was to use the Pathfinder Helmet as an Ornament. But to my surprise I wasn't able to unlock the Helmet in the Appearance Customization, I've dropped the Helmet at least 3 times from different Sources and it's still not there, additionally I tried basic stuff like equipping them, waiting a couple of days and restarting the game. The Helmet is unlocked in the Collection.
