I like the Black mixed one. The Cat one looks decent if it wasn't a gif it just seems it's one of those hats you'd get form a hat shop like Nexus or something. I just dislike the third mixed hat seems oversized and idk what is going on with the goggles.

I like the red iDevice hat and the GST engraving looks neat. The frog one yet again seems oversized like the kitty one but oh well. I like purple in terms of originality but i'd be bias in my opinion because i hate hats/masks that cover the face.
