We have a couple of cool bags but they are a bit shit tbh and certainly no good for the 4-7 day camping trip we plan this summer.
There seems to be such a range in price for these though and I'd be interested to know what the difference is and whether it is worth paying for an expensive one.
Also the plug into the car cigarette lighter ones - do these have to be plugged in the whole time (and if so how does the battery not wear down?!?!!) or just when you are out and about?
Cheers in advance!
