A really nicely made item. With the ends at their minimum I recon it'll take around 20 litres of kit which is important as it's a bit wobbly when loosely a packed load. Ram in a load of stuff and pack it tight with the end straps and it works just fine. If you have a rack, it comes wth straps to mount it, if not you'll need a fitting kit. I have the kit for my stripple and it makes mounting and removing the bag really easy. You can also stack other Kreiga bags on top using the loops on this bag. I'm very pleased with this bag as it has proven to be quite versatile. The shoulder strap makes it easy to carry when not on the bike.
