Hi Guys,
I was looking for more reviews on Geigerrig's Hydration Engine when I stumbled across their Virus Filter which apparently weighs nearly half that of a Sawyer MINI according to the specs on each of their sites (I own neither).
Claimed Weights
Geigerrig Virus Filter – 1.05 oz.
Sawyer MINI Water Filter – 2 oz.
That said, the Geigerrig costs about $15 more and only handles ~100 gallons per filter cartridge, however unlike the Sawyer it also filters out viruses.
Thought I would share as I didn't find it when searching the forums.
