the Nalgene Oasis Everyday, 1 liter is robust, super processed, the lid closes tightly - and it is exactly the same size and shape as the standard military canteens the US Army and fits in all of these canteens appropriate bags. and the bottle does not smell like plastic or even does not smell and is BPA free. I am absolutely satisfied with the Nalgene water bottle and can wholeheartedly recommend it!
