For the last 3200 miles, I have been carrying a liteflex swing trekking umbrella. 3200 miles is 2700 more miles than any other umbrella I have carried has lasted. It has some holes at the top of it and the silver is wearing off but structurally is still good. The silver coating is to reflect the sun back. It weighs 7.8 ounces (220 grams) and has no logos on it.
I don’t carry poles and I don’t mind holding it in my hand but if you do mind, “Switchback” has this idea for an umbrella holder.
