As a noob backpacker (really new) sorting out hydration options I've been intrigued by the Geigerrig system.
At $59, not so much. But they are at the SLC Costco for $29 for the 2l size.
I was thinking of putting a Sawyer Mini outbound of the squeeze bulb and using the bag for dirty water and lashing it atop my pack.
I am a bit concerned though at the prospect of bacteria growth in the bag.
Not many references in older posts for Geigerrig here but I'd welcome input on this thought process.
