## Our verdict

### Reasons to buy

-   Weatherproof construction that would protect your stuff from outside elements.
-   Has lots of attachment points for outdoor stuff and/or accessories.
-   The harness system is truly comfortable to use and versatile as it is also adjustable, providing a better fit for seemingly everyone.
-   Made specifically for bikepacking which eliminated the hip wings, has a slender figure, and helmet fixing.

### Things to consider

-   Has no external pockets for handy things.
-   The zippers can be a bit sticky but that's because of their waterproofing properties.
-   Access to the main compartment requires you to take off your bag.
