ride long? out into the bush? does it(it what?) rain sometimes when yawl ride out? remember the space blanket? now stop grinding your teeth!
Walplastic has a plastic blanky in stock over in paint-paint removal with a plastic of considerable quality considering the cost for a 9x12 plastic dropcloth. This film is durable, relatively free of water entry holes when new, and of a size that allows comfort under a lengthy downppour: avoid hypothermia!! The package is 'small enough' to fit into one of dem underseatsaddle bags.
you can smother your little sister with it! with a rope,and a few sticks to pin the sides down- a tent tarp!
