A running pack that also works very well for bikepacking ultras. Masses of small stash pockets that won't spill gear when the going gets ragged. The 14l capacity is about the same as an large-ish seat pack.
The pack is lightweight and high capacity, a comfortable wrap around style with full compression allow for the lowest profile empty or fully loaded. The Zygos 4.0 can be used with a 2L reservoir, 550UltraFlask, or softflaks (not included). Expandable mesh on the back panel gives 4 liters of extra capacity as well as storage in the front with extra pockets.
NOTE- the ZYGOS does not come with bladder, like in the photo.
