I have some international travel coming up (France, West Africa), and I'm sold on the idea of having a light coat or jacket that I can wear on the plane and that will have plenty of secure pockets for documents, phone, etc. One option is something like an Orvis travel blazer (I suppose even just an Anderson Little blazer might in fact do the job); there are also more military-style jackets.

I like the look of many of the 'chore coats' that lots of companies sell, but I don't think the pockets on those are particularly functional, and at the very least I need something with inside pockets. I do own a Barbour Beaufort, but I find it too heavy for travel purposes like this unless I knew I was going somewhere cold and wet, which is seldom the case.

Any preferences?
