Transmitter Jacket

[ifuonlyknew]

So there is this big race coming up in January, and the track is outdoors. It's gonna be really cold. I remember seeing a "Transmitter Jacket" on a UK site. I can't remember where though. Perhaps one of you guys know where I could find it? I figured it was probably a site that somebody here frequents. If its any help the site had jackets for stick radios, and pistols too. Any help is appreciated.
Thanks.
