What are dimensions of this rucksack? I want it for cycling around town and getting the shopping home. Will it fit six bottles of wine?

Not sure on the dimensions (off the top of my head anyway) but it is comfortable and dynamic, Its a Medium sized bag and i use it mainly on my Motor bike for the same reason (carry shopping etc) and yes it should fit 6 bottles of wine in. The back wall is well padded which makes it good for long journeys, the side pockets are absolutly useless tho.
