I never understood the Nalgene hype. The wide mouth is awkward as hell to drink out of (especially when moving), and there are no advantages whatsoever.
>>551761The expiration date on the bottle is for the liquid, not the bottle. The gas barrier properties of PET aren't great. Oxygen diffusing into the liquid causes issues with the liquid spoiling eventually. Not a problem if you use it every once in a while.
What are Nalgenes made of nowadays? The Bisphenol A in those older Polycarbonate Nalgenes sure isn't healthy.
