Old Saying: No matter how far down the wrong path you’ve gone, turn back.
David T: Thanks for the detail about your “sunbrella”. I have been tinkering with umbrellas for a couple of years. I’m not 100% happy with any of them (yet), but I often carry some kind or another.
One of my favorites is the Umbrella Hat that I have discussed elsewhere. The one that I like best so far is small-ish, like 24″ across if I recall correctly, has a soft headband (important), and no vent (the vented kind adds weight with little added functionality). My hat is good up to about 7 mph wind. I have added split-rings to the tips of four of the spines so that I can quickly clip on guylines for stronger wind, although my testing has been limited.
I also carry a MontBell Rain Umbrero. It’s super light (<2oz) and packable, works for both rain and sun. It has a unique harness that keeps the hat entirely off my head for maximum ventilation, and it also creates 4-point guylines for wind resistance. It is a candidate for the “world’s best hat”.
I’ve never been quite happy with lightweight umbrellas attached to my pack. I love your cargo shirt+epaulets idea but, as you say, there are always cases where I cannot adjust the thing the way that I want. I don’t want to sacrifice a trekking pole to carry the umbrella in my hand, so I remain frustrated.
The most satisfying thing I have so far is a “chair umbrella“. It works very well, but the clamp is heavy, so the entire thing weighs a pound. That’s more than double the weight of a lightweight umbrella, but it works. Tradeoffs.
Terry’s photo looks a bit like the chair umbrella, but it might be lighter weight than the 7 ounce clamp that mine uses.
