TL,DR:
Good - durable material, functional for cyclists, hood affective against wind, very compact. +4 stars.
Bad - unclear folding strategy, hood tiedown velcro is barely functional, zipper feels a little fragile. -1 star.
The four stars are for the extreme portability and good functionality. The nylon feels strong enough that I'm not worried about a tear while cycling around making deliveries, and the hood is shaped well to keep out wind. It all folds down into a size small enough to hold in your palm.
The missing star is because there is no clear method to folding it, or carrying solution once you've folded it down. I use a rubbber band.
