>>2354864A poncho. I used a plastic emergency poncho last year in a low-risk environment and it worked better than my frog togs jacket. There’s a poncho on Amazon made by a company called One Wind that has some unique features, namely an adjustable hood for different head sizes and a belt that pulls the extra material tighter around your pack and stomach. It’s also pretty light at 8oz. But for $31 I just don’t trust it.
