I bought this rolling duffle for my dive gear.  I specifically puchased this one because I already own another type of Delsey Duffle (the Helium 2.0) and the fabric is very durable, as is the entire bag, handle, wheels, etc.  I liked that this had wheels that were not sticking out (they are sort of recessed into the bag), this way they won't break off at the airlines.  This bag truly is VERY LIGHT, which is another reason I chose this bag for my dive gear, since dive gear can weigh alot, and with airline restrictions at 50 lbs, this makes it very useful for heavy items without adding bag weight.  Even though the bag is very light, it is VERY durable.  This bag does have a hole where the zippers meet so you can lock up the main compartment.  This bag also has a built-in luggage tag holder, as well as a shoulder strap (removable).  I fit my BC, 25" fins, mask, snorkel, regs & gauges, wetsuit, skins, and some other small stuff, and it weighed 27 lbs.  It will also hold larger dive gear.  I plan to also stuff some bathing suits in there as well, to make my carry on bag for clothes a bit smaller & lighter!
