Hi, recently took Soylent on an airplane trip. 1.4 is fantastic for travel. As others have done, I asked for a cup of ice from a vender and mixed a great bottle of Soylent in the bathroom. I've been using a Klean Kanteen sealed metal bottle, which I love, but the lid's diameter is too small to pour a scoop of Soylent into without making a mess.
What do you guys recommend for Soylent on-the-go? I have no desire for blender balls, just something that is airtight (I can shake without spilling) and has a wide mouth/lid. Thanks!
