The Hill People Gear Tarahumara is a unique pack in that it is very compact (about 900 cui) but has a harness system that can support loads far heavier than you can typically stuff into that small of a pack. This makes it something of a blank canvas for users and makers to develop ways to expands its capacity.
Mel Terkla of PocketUp recently showed how their pockets can be used to expand and organize the Tarahumara pack while still providing access to all compartments. Two Handy Pockets are hung from the upper tabs and compressed by the Tarahumara’s compression straps. These are PocketUp’s 1000D Handy Pockets but any of their large Handy Pockets would fit with the same proportions. There are plenty of hardware choices that can be used to hang the pouches in this manner like ITW GrimLocs or Slick Clips.
Additionally, he has attached a Mini Pod to the bottom of the pack. The Mini Pod would attach easily to the Tarahumara’s existing lower tabs, instantly adding compressible storage for items like light insulation or shell layers. We have previously discussed the Mini Pod here: Mini Pod on JTT
