Do you prefer your water bottle to be made of metal, plastic, glass, or something else? Straw or no straw? How big would you want it? Should the bottle taper down in the bottom, or do you think the sided should stay vertical? Are any of you one of the few people who would like that weird rectangular bottle? Or maybe one of those squishy fold up ones for travel? No handle, flip up handle, mug style handle, or little loop?

I seem stuck using nalgenes. They’re not great. I tried switching to glass carafes but it didn’t work out. The metalic lids would rust out on to the lip and could not be cleaned. The nalgenes are durable(ish) and versatile which keeps me stuck on em. 1 liter is the perfect amount of water, the loop on the top is a nice low key handle, and they’re water tight as anything, even when the threads have been smashed. Just forget about the microplastics.
