Thanks for the info ben, I carry an umbrella during the week, I have to park down the street and walk to the office, so in the mornings I have the umbrella in the truck for the walk to the office, and can use it and stay dry if it's raining. I carry it to the office even if it's not raining, in case it's raining when I leave the office and I can use it to stay dry on the walk back to the truck.

Unfortunately I doubt the umbrella would be as convenient or useful on the trail lol
