I doubt it's only at Spirit. Pilots are a fickle bunch. Everything else you said I agree with. It's nice to have options. It would be equally nice if this pilot group would not judge others for their choices. I mean, who gives a hoot who wears long sleeve shirts, blazers, leather coats, or North Face jackets? As long as it is approved uniform attire, rock on! If someone is not wearing approved attire I get it. I personally do not like acting as the uniform police, so whatever. But I totally understand if someone else wants to make that call. Personally I think the Karbon jacket doesn't really work, for me. If it is approved and you want to wear it, have at it. I think you look smashing in it. The last time I personally judged anyone for their outfit was sometime in the 80's when in high school, and then it was because of their choice of spandex!
