waterproof / breathable poncho?
 

well yes I am asking..

would anyone know where I can buy a waterproof breathable -preferably lightweight - poncho?

and has anyone used one?

thinking that if I could find one of these my camping / riding kit would be complete.

My idea is that I could use one while riding if I get caught in a summer rain,

And use it as a shelter tied between our bikes if we end up in the middle of nowhere and can't pitch the tent up,

And use it as an outer layer / fly sheet for the lightweight single layer tent I am using.
