Having been washed out of my normally trusty vango banishee a couple of times last year, I'm thinking of getting a bivvi bag just in case so that I don't have to shelter under a bottle beer top. Looking at army surplus BUT do they have a zip or do you have to hop about like a solo three legged race participant and then try and crawl into the tent like a demented caterpillar once you've fallen over ?
