Ortlieb Zip City Messenger review

This 24-litre bag features Ortlieb’s Tizip closure, which renders it throw-it-in-the-river waterproof, so it’s a great all-year-round choice. 

The zip uses a silicone lubricant, which you don’t want to get on your clothes or documents. It goes up to 11 for rain-resistance though!

Inside there’s the bare minimum of organisation, but if you want a real workhorse of a bag that’ll last, it’s got the pedigree.

The slippery fabric makes the optional sternum strap a necessity for use on the bike, but once it’s fitted the Zip City is nice and stable.
