I own 4 different scottevests. The best one I use while traveling anywhere under all weather conditions is the one below that comes in a men's and women's version. It's the lightest weight of all of them. All polyester and easy to wash and doesn't shrink.

I put a surface go, mouse, two phones, selfie stick, lots of cables, chargers, water bottle, and all kinds of small other items. I keep everything that is valuable in that jacket in the event of an emergency where I won't have access to my carry-on. I wear it the entire flight. I plan to purchase another one in a different color next year. Black is the best color overall.
