My silver umbrella has quickly become one of my favorite items I carry.
It is a saving grace really.
I carry a Euroschirm trekking umbrella (found on sale at Campmor)
It folds up smaller than the Golite umbrella and the weight difference is neglible.
I walk degrees cooler through the hot desert under my umbrella.
A shady area is magnified by adding my umbrella. Where no shade exists, it provides some comfort.
The first time I popped open the umbrella on a hot, dry, shadeless day, I did feel momentarily ridiculous. However, the instant relief from the pounding sun changed that thought to delight at the inventions of humans.
