Haha!
Two years ago I bought in Germany, a really nice hi vis winter jacket, Lots of useful pockets, very warm, and of course the lime green and reflective that European airport operators seem to like. The airports I frequent in Canada apparently could care less, in my experience.
I do like to wear it for my winter flying though, simply because both my planes are white, and if I end up in the snow somewhere, I would like to be visible myself (as well as warm).
I also wear it in my capacity as a volunteer firefighter, as (I presume) it meets the requirements for roadside visibility. The Chief says it's good enough for him.
The other night, I was flagging traffic for a roadside accident. There am I, with my super bright jacket, and super bright LED Lenser flashlight, and motorists were near running into me. After the call, one of our Captains came to me, and commented that several motorists complained that I was too difficult to see!
Therefore, I now refer to the super bright jacket as my "cloak of invisibility"...
