I have been using my duffel for 6 months or so now, and I can report that it is nothing short of fantastic. I waited a while before leaving a review so I could really road test it.  Switching from a "roller board" style of luggage to a duffel was a great decision, because this bag is so light and easy to use, even when it is fully packed.  I love being able to stuff it into any overhead compartment and not having to check my bag.  The shoulder strap is comfortable, and I absolutely love the separate shoe compartment.  There are just enough pockets to use for various applications, and I have yet to run out of space on even longer trips.  The bag is really well made and has shown no sign of wear and tear over 6 months of fairly heavy travel usage.
