Hi All, apologise if this has been asked before, any recommendations for a soft bike bag for a road bike?

Staying in Berwick upon tweed in a weeks time and am going to chuck the bike on the back seats as the dog will be taking up the boot space.

Might not get it in time, but love my ground effect bags.
Alternative for next week would just be an old duvet cover

Do you have a decathlon near you?

I have a folding bike bag just for this purpose. Zero padding (have flow with it added my own padding) but light and perfect for carrying bike in car plus folds up when done.
