Not sure of the reliability of this story, but I heard that the wife of the Hydro Flask owner divorced him, took half of all of his production resources, and restarted manufacturing the exact same products at a discount, re-branded as "Fifty/Fifty". Lol..
If that's true, then not only are you getting a "Hydro Flask" at a discount, but it looks like Sportsman's Warehouse is currently selling the 18 ounce version at Half off.
Fifty/Fifty @ Fifty% Off :-)
Black, Grey, and Lime are still available at the time of this posting! Nalgene-Style lid.
