Oxford Aqua B-25 £59.99

A really robust rolltop rucksack with two tiny outside pockets (good for slipping in paper, not gloves) and two fractionally larger mesh pockets. Easy to adjust to get a comfortable fit and it’s good on the bike, though the load can move when riding - especially when partially full, as there are no lateral load-adjusting straps, just the rolltop-securing compression straps. Tough tarpaulin construction means it’s totally waterproof though.
