Umbrellas are not a "new popular accessory" just because more image conscious people are using them now. They have a long history of being an accessory men would be willing to spend a lot of money on.
A good umbrella should be heavy and feel very solid. Most umbrellas you see today are cheap because people think of them as throw away items. They think everyone always loses an umbrella, so why spend money on it? That's true for most people, but not if you care about it. Like a good watch, flask, or shoe horn, it's likely an umbrella will be with you your whole life.
