That merch video was interesting! My #1 request has always been for an actual runDisney, dri-fit RUNNING hat with a detailed Mickey embroider (not the current weirdly proportioned silhouette running Mickey blob)... not a baseball hat. It never happens. (All the current runDisney hats that I've seen are heavier, baseball-style, with that little button on the top - not running hats.)
I have an old, old white one from probably 15 years ago and every time I wear it at these races people stop me and ask me where I got it....

Hint hint, Disney merch people!
(Edit because I went down a personal tangent rabbit hole:
This is the brand and style of my old white runDisney hat (although the mesh venting style has changed a bit vs my old one)! GO MAKE NEW ONES DISNEY lol)
