As above. I've looked at a few but nothing seems particularly highly recommended. The Ortlieb system seems to be a bit off a faff to attach the backpack 'carrier' and some of the others look as though the clips might dig into to your back. Looking for something around 18l. Not particularly excited if it doesn't exist but didn't want to miss anything obvious before giving in
Yep. The bug is looking like a winner at the moment but it is indeed pricey. A better option might just be a humungous pannier and sling a regular backpack into it
