I used to have a Belstaff jacket (a million years ago), but it was the 'modern' nylon variety - no armor, and a stupid belt that just got in the way. I like waxed cotton stuff, and have a Barbour jacket for off the bike, but for wet riding I am a total zealot for the Aerostitch stuff. It is incredibly well designed - obviously refined over a lot of time - to do what it does well.
For example:
-The "belt" is velcroed, and cinches the waist, but never needs to be fastened when you're zipping up the jacket.
-The flap that stops the rain from entering the front zipper never gets caught in the zipper
-The wrists have a velcro tab that lets you adjust size, and a zipper that makes it easy to get on and off. No dumb snap at the cuff
-The neck closure uses a velcro tab also, which allows you to adjust the neck opening depending on whether you're wearing a neck tube & turtleneck or not.
-There are hand pockets you can just slip your hands into without unzipping anything, but the rest of the pockets are zipped and flapped to keep stuff secure & dry
-There is a chest pocket that is big enough to store a folded full sized map. Plus a sandwich. Plus a small child I think.
-The right sleeve has a small zip pocket that is just perfect for carrying bridge toll money
and on and on... you get the idea. Good stuff, well made. Costs a fortune, but lasts forever.
