Comments: I got this backpack in March of 2012.  I was primarily interested in using it to transport my skate gear from the US to the UK when I went on vacation and skated a club marathon race in London.  This is a great bag.  The outside is very durable.  There are two main compartments on the inside of the bag.  The front part is separated from the back part with a mesh.  There are clips all over the outside, and there is another pocket on the very back of the inside of the bag.  This pack traveled internationally very well, and I used it as a carry-on.  I kept wheels on the outside straps.  Overall, this is a great pack that is worth the money.

My only two complaints are the straps for the wheels on the outside and the mesh on the inside.  The straps on the outside loop through D-Rings at the top of the pack.  They are nylon straps, and are very durable, but the D-rings on my pack were very small.  The straps are folded and sewn, and the extra bulk means they don't fit through the D-rings without a lot of wrangling.  I cut the straps to a point and melted the nylon to seal the ends.  This works much better.  Also, the mesh on the inside is weak, and has torn down the middle.  This was caused by my lifting the bag with stuff in it by the middle while the zippers were open.  Avoid lifting the bag like this.

Otherwise, this pack holds a lot of stuff, is very durable, and I look forward to using it for years to come.
