Alpine Threadworks has a nifty tarp that also converts into a bivy sac or can be used as a winter rescue "toboggan."
Check out their website.
I don't find silnylon has a limited life. I use mine (Integral Designs) about a hundred days a year minimum and it's going onto its sixth year without issues.
It's been used in tropical sun, summer downpours, and winter over a snow kitchen. No wear issues and it doesn't drip...
