If you think a USB-rechargeable battery operated fan is a worthwhile addition to a holster whose claimed primary reason for existing is that it's "more comfortable" than a plain kydex rig, you need to go sit in the corner and feel bad about yourself while the rest of us point at you and laugh.
Like Joshua H. brought up on the Bookface, this might have potential for hilarity:
Guy: "What's the noise?"Maybe if strapping a huge swathe of something to your side makes you sweaty and uncomfortable and gets your buttsweat all over your gun, the solution shouldn't be electric fans and cooling ducts, but a holster that is much smaller and waterproof?
Alien Gear wearer: "What noise?"
Guy: "That humming noise. It's coming from... your belt? What is that?"
AGw: *fitfully tries to conceal his poorly fitted holster* "I don't know what you're talking about man! Just leave me alone you weirdo!"
I mean, I just drove from Indianapolis to Shawnee, Oklahoma with a Dark Star Gear Orion holster carried IWB, and that was something like ten hours, only stopping to pump gas. No cooling fan required, either.
