Shimano Tokyo 23 urban daypack



A comfortable and versatile bag with excellent waterproofing, but this quality comes at a price

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

The Shimano Tokyo 23 urban daypack is a really useful utilitarian rucksack that can fit in a huge amount while being comfortable on your back. It's a bit pricey, but includes some strong features.

  • Pros: Good waterproofing, loads of storage, hardwearing
  • Cons: Expensive

As the name suggests, the Tokyo 23 has a 23 litre main compartment, with a roll top – which means that it can hold a huge amount of stuff, and because of the relatively unstructured construction on three sides, it can hold most things even if they are a strange shape.

In addition to the main compartment there is a large pocket at the front, which also has some small pouches within it, including a zipped section and three smaller pockets. This is particularly useful for keeping smaller items or items that you need to access quickly – so I used this predominantly for my phone, keys, wallet and so on. There are also three large Velcro straps on the front with six fabric loops, and a set of loops on the side of the bag designed to hold a D lock.


Within the main section there is also a zipped netted pocket and a larger pocket that is useful for things like tablet computers.


Down the sides of bag there are two full length zips, with the left side giving side access to the main compartment, but the right hand side is a large padded laptop sleeve, more than big enough to hold a 15-inch laptop and sufficiently padded that I didn't feel it against my back when riding.

There are two closure systems used on the bag – the roll top and fully taped zips throughout. The zips are all easy to use with large and easy to find string tabs so it's simple to use even if you're wearing thick winter gloves or if they're soaking wet.


The roll top also works well and is secured with a large buckle that fits through one of the four loops at the top of the roll to make the roll larger or smaller depending on what's in the main compartment. This system works well and is as waterproof as the taped zips, plus Shimano has sewn magnetic strips within.


The only slightly annoying thing is that when the buckle is tightened onto the smallest loop or when it's not attached at all, it gets in the way of the zip of the large front pocket.


The bag is comfortable against the back thanks to a decent level of padding and the mesh material used to minimise heat build-up when riding. This works relatively well, although I have used others that are better in this respect.


The straps are also comfortable without being overly padded, and sit well on the shoulders. The chest strap also keeps them in place nicely.


As well as being comfortable, one of the strong elements of the bag is its protection against the elements, and although the bag is made from water-resistant ballistic nylon, Shimano has also included a high-vis shower cover. I took this out in heavy rain several times and didn't notice anything getting through. At the bottom Shimano has used a tarpaulin material to make sure nothing gets through there either.


At £119.99 the bag is certainly a big investment and comes in more expensive than some competitors. For instance, the Craft Cadence IPX5 comes in at a penny under £70 and the Rivelo Coombe Dry Rucksack is £20 cheaper.

Overall, though, I was really impressed with this bag. It has a huge amount of utilitarian features with enough pockets, straps, and compartments to fit everything you could possibly need. It also has some good high-vis elements and the waterproofing is excellent. However, all this quality comes at a price that may put some people off.
