Hello all, I was wondering if anyone has one or has tried one of theses I have just been given one and im wondering what they are like? I wont be trying it now until next year as its only 2 season. It doesnt have alot of information printed on it but I have googled it and got some information and some mixed reviews. I have never used such a lightweight bag before im used to my Vango 3 season bags so any comments appreciated
