A pure basics, all-dry soylent to store as a powder mix. Just add water! Specially formulated for backpacking/camping/hiking where space and weight are at a premium in your pack. But it would work as a daily soylent too.

This has not yet been tested. I can't vouch for the taste at this point. I have never done an oat flour based soylent before. But it's a popular format, so hopefully it's alright.

When I do a test I will update with information on scoop size per bottle. i estimate it to be just under 1 cup for 4 bottles a day (thinner), or just over 1 cup for 3 bottles a day (thicker).

In theory you would pack 1 blender bottle for soylent and (at least) 1 separate water bottle, a water filter for additional water on the trail, and ziploc bags with a 1-bottle-sized portion of this soylent mix—however many you need for however many days you'll be out. Remember to drink plenty of plain water in addition to your soylent, especially if you're hiking all day!
