The zPacks Zero Cuben Backpack is really a stuff sack with straps. Mine has two options:

1. External water bottle pockets (because I often need to carry lots of water in the desert).
2. Sleeping pad holsters. These are removable, and I only use them when I am using a GG NightLite sleeping pad. This is the easiest way to carry this kind of pad. I remove the holsters if I am bringing a rolled 1/8″ pad to protect my NeoAir air mattress.
3. Additionally I made a sternum strap out of some Tripease cord and a couple of mini-biners, because the straps tend to slide of my shoulders.
