Raincover for Stroller

[station4]

Does any one remember the old fashioned rain ponchos that used to go over pushchairs? I know my mum had one when i was little. I have seen some in the shops but they are either red or navy. Does anyone know anyone that sells more modern ones? Every pushchair i have had (son and daughter) when they get to about 2 their feet stick out the bottom of the cover and they end up wearing wellys everywhere it is driving me mad as my little girl is only just three and is getting soaked!
