I got this to pair up with a Guyot/Nalgene Standard, nested inside a Maxpedition 12x5 carrier.
The Solo provides versatility in that it fits over a standard 1L (or 38oz) bottle.
In use, allows one to cook in one vessel while consuming a beverage, or cooking something else, in the other one.
The Ti construction seems durable, but I have not had an opportunity to "stress" test it...
