I never used to take an umbrella when I travelled, but over the last couple of years I have changed my mind.
I now take a folding umbrella like this one for a few reasons.
If you are crossing a road a hood can really restrict your vision . . . . . which becomes more important when you are overseas, and might have forgotten traffic may be coming from a different direction.
In the tropics a waterproof jacket can get very hot and sweaty.
A much better combination is a T-shirt or Polo Shirt with an umbrella.
Appreciation of surroundings
When I am in a new place I am constantly looking at things around me.
With an umbrella you only have to turn your head to see things, not move your entire body.
Since I had a cancer removed from my chin I am more conscious of the effects of the sun and the umbrella can provide more shade.
Well it’s only a few hundred grams, and it fits in my coat pocket so it doesn’t count in my carry on weight total.
