Listen, I guess you are flattered by all of this attention. But you would rather have your questsion answered, i reckon. If you have 90 quid to spare, go to Transair, and but an " Aviation Industries CWU-45/P"
I have one. Its warm, has all the pockets and pen holders you will ever need, its light, its durable, looks great and can handle a regular walk round and then being slung on the back seat of a PA28 for a few hours. In short, there are loads to choose from, but this will last you years and years. It also has the sort of look that will get better the more you wear it.
Regards.
