The Koodi is pretty rubbish, looks very taut in the stock photos but just sits all saggy and billowy in reality, wonder if they airburshed it? - I've tried it on following:
Silver Cross Pop
Landrover ATP
Nipper
Urbanite
Bee
It doesnt fit three-wheelers, but fits the Pop well, quite low at the front to cover feet, so I guess best for that type of stroller.
Fabric is waterproof in a downpour but eventually the water weighs fabric down so that a wet cover is against your child's legs.
Good idea having a pouch attached that it folds in on itself to that you can also clip onto the frame to save basket space though.
The roll-up view/access window is huge. Good.
Attaches by several velcros.
Very dark in there, makes for a good sunshade or sleepshade though.
There's some on ebay for less than a fiver at the moment. They're nearly £18 in Tescos :o
