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.
