Rain Cover for the Aloha/Cart set up.
If you have a Zuca/Aloha set up then you need a rain cover
Just in case you might get caught in the rain this is very useful. It will pack small and cover your entire set-up.
The hole on top is designed to fit around your wrist not the Zuca handle
I have one in my kit at all times. They are well wort it but in a pinch a large trash bag will work.
