Needed a carry-on approved bag and after a lot of research I decided to try out the Farpoint 40 M/L. It fits all I needed for my 4 week trip motorbiking across Vietnam. It was very durable with no wear or tear and was also very comfortable to walk around with for long distances. It sits on your hip very nicely and the ergonomics of it was perfect. It kept all my items inside such as my two cameras safe however I did have clothes to create extra padding. Lastly when I was riding down the mountains of Dalat, it was pouring down with rain for the 1-2 hours and the outside of the bag looked soaked dripping and when I opened the bag it was completely dry inside.
I researched "carry on" sized travel packs for about 2 weeks and finally decided on this one. The only down side is that I now realise I wasted 2 weeks researching "carry on" sized travel packs and should have just bought this one in the first place. HEAPS of positive reviews on it already and now I see why. You can also see it on youtube. I was hesitant about getting the red because in the pictures it looks quite bright but it's actually a bit of a darker red and looks great. Very happy with it.
