also note THEY ARE SUPPOSED TO "LEAK" - that's how they work
The water that 'seeps' through the bag actually cools during the evaporative stage, which in turn cools the bag and contents - same principal as any evaporative cooler
Why a lot of people hang them off the front bullbars is that the air that hits the bag during driving also helps with the cooling process ( and it saves the back
seat getting wet if you tried leaving them inside :-))
How do I know all this?
Well being a Kiwi I had never seen a canvas water bag until I came to Oz. So wanting to ensure I was 'suitably equipped' I too bought a canvas water bag (still can get them from most camping and BCF stores) did all the 'seasoning' as described in the 'operators manual' and, full of expectations, filled it up only to see water seeping through the canvas.
So I went through the seasoning process again - same result
Applied some Kiwi ingenuity and sprayed the entire outside with, spray on waterproofing' - still 'leaked' so threw the stupid thing into the rubbish bin
It wasn't until some years later when I was on a trip and had about 6 mates sitting around a
camp fire all telling stories (both true and false - as you do) and I told them the story about 'that stupid canvas water bag' that I threw into the bin.
Couldn't understand why they were all rolling around the
camp fire laughing like bloody Hyenas !!!!!
Needless to say I have now bought a 2nd canvas bag and use it with pride :-))))
