Shimano's Unzen 4L offers a strong compromise between minimalism and practicality

Our review

Practicality is at the heart of the Unzen and makes it ideal for long trail missions where descending takes priority

The Unzen from drivetrain pioneer Shimano is ideal for people who like the idea of harness-style minimalism but would like a bit of added practicality. The lower straps feature Velcro adjustment and a hook and loop system closes the pack in around you. That little alloy hook also makes it incredibly easy to get in and out of making the goggle loops and exterior pockets all the more useful – handy if you dabble with enduro.


A removable waistband for added stability is also provided should you really get her loaded up but the Shimano stays confidently in place without it. A fleece-lined gadgets pocket, separate netted bladder storage, a rear bottle pocket for shorter rides, tool compartments and light loops add up to a clever pack.


There isn’t cavernous amounts of space aboard the Unzen – it’s more of a ‘a place for everything and every thing in its place’ kind of backpack. A slight flaw is the side-only access to the (snug) main pocket but as a compromise between minimalism and practicality, the Shimano walks a convincing tight rope at a keen price.
