After searching hundreds of rolling duffel bags online for the right size, weight, durability, I bought this for my college age son to make carting clothes, laundry hamper and backpack from car park to dorm room easier (great roller wheels, which are replaceable) - plus he was going on a snow trip to Colorado. Well I can tell you he loves it - it has an incredible amount of room and the end pockets easily take a pair of winter boots.  The side pocket has ample room for toiletries.  Still had room for more after packing for a 5 day trip.  He loves the fact you can use the well concealed straps and make it a backpack too.  It folds flat for storage (a biggie) and is made of tough fabric and heavy duty zippers.  Love the bungee cording on top too for any awkward last minute items.  Lastly, a great looking bag, nice deep blue color.  In short, best bag ever.
