Does anyone know what this bag weighs,and how big it is both folded up and opened out?
It weighs 740grams (on my kitchen scales).
The sealed bag it comes is 37cm x 33cm which folds again and fits snugly into my rear pannier.
Sorry, can't help with opened out size, except to say I wheeled my 21" touring bike into it at the airport and it seeemed huge - like there was room for two people inside as well !!
