I decided to add preparedness oriented gifts in addition to my normal restaurant gift card this Christmas... I thought I would share my choices, as neither has a visual size reference in their on-line pictures... not that small size is a bad thing... the Sawyer mini filtration system comes with a 16oz gray water bag, both are shown relative to a .5L water bottle... additionally the Feuerhand kerosene lantern is considerably smaller than my Dietz models.. although it is 2x to 3x more expensive than a comparable Dietz, I'm impressed with the clean flame, and especially the light transmission through the Pyrex like globe....closer to that of a Coleman mantle lantern than the Dietz "Mason jar" glass globes....
