Givi EA104B £57.99
Ultra-slim rucksack expands to be merely very compact and it couldn’t fit our laptop. The trade-off is that it’s almost unnoticeable when riding, the harness adjusting comfortably and holding the load in place. The rain cover folds out from the top so stays on at speed, but is needed as the material around the zips soaked through on the shower test. It has a secure helmet carrier but the one tiny external pocket is on the waistbelt - hard to reach when on.
