I use a driducks poncho with a DIY version of the JRB weather shield mod. It was cheap and has been very useful as a UQ protector and numerous other things. Dri ducks does breath better than silny in my experience and is comparibly water resistant. They may not be as durable, but I haven't ripped my poncho yet, can't say the same for the pants. Though its an easy repair with gorilla tape when its dry good doing that with silny.
