I have come across two good products for carrying the water during expeditions. I wonder which of them would be scientifically better to have along.
Yes, I agree that this question may sound like a primarily-opinion based question, but I want to get the pros and cons of the two materials.
A hard-fiber can or an alloy/aluminium bottle. Does altitude/weather make a significant impact on selection of the bottle? A Hard Fiber one or an Aluminium made?
NOTE: When empty, both weigh almost same.
