The Fox evolution weighs 6.5 kilos and can be set up in less than a minute. A good brolly can weigh 4.5 kilos, so there is not much difference in the weight.
The bivvy offers you far better cover and can keep your gear totally dry, my gear ended up soaked, muddy and weighing what seemed twice as much as when I set off.
I will take my bivvy next year when I go next year.
