Every morning I blend a 14oz bottle of Soylent 2.0, two bananas, and ~20 ice cubes. I then pour the resulting slushy into a 40oz Hydro Flask bottle, nearly filling it to the top! I'm able to stretch my consumption of a single 14oz Soylent so that it lasts most of the day.
Try a single bottle from amazon or if you're ready, jump right in with a 50% discount on a 12 pack from the official site.
