I bought the transition jacket when it first came out, but I must admit that it is very pedestrian as a uniform piece. It is great this time of the year, but I wear my hat whenever I wear the transition jacket.
Anyway, it won't bother me when they officially remove the transition jacket as a uniform piece. I'll keep it for personal use.
What I would like to see is a good rain coat... one that is not too big and clunky. I used to have a 1960's NWA rain coat that I used to use at the regional I flew for. I think it was made by London Fog. I don't expect high quality material like that, but I would wear a simple rain coat instead of the transition jacket.
