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?

Nalgenes are solid, usually polycarbonate so can handle a few knocks without disintegrating, but a point of contention is that they’re not insulated.
For summers I’ve got a 2L Wild Roots insulated flask that has withstood enough time on the jobsite to gain a few scratches, no serious dents as of yet
