Ideal for protecting the car from oil and mud - it's made from a PVC backed high density nylon - and for carrying your Brompton folding bike on the train. You may wish to provide extra padding for air travel, but at least you can stuff the case in your rucksack and pedal away. A useful soft case in it's own right. 600 x 600 x 200 mm external. Only suitable for Brompton or Dahon Curl.
