I like baseball caps and other types of hats, and I got a few in my merch collection. Here’s one with The Cog:
Not everything in my merch collection is 501st merch. While The Cog is often used by the Legion, it is not a Legion symbol. This Cog is a generic symbol representing The Galactic Empire, and is also known as The Imperial Crest.
The brand is Flexfit, and my trooper ID is embroided on the back. I got it from Trooperbay.
