This is a great bag, its the Ion Core, 1/3 Gearbag. The bag itself weighs heaps less than any other bag I checked on scales, the empty bag weighs just 3.6kg, and all of the other "golf type bags" weighed around double this, or a tad under double. The bag is not padded all over, unlike all the golf bags. I traveled to 3 cities on the east coast recently with some interconnecting flights, so it got a workout.
There is a Zephyr in one of the shots, biggest kite I own, and 2 others easily fitted plus a 1.37x41.5TT, and its weighed in at the airport with my harness shorts rashie towel and pump with one bar at approx 22kgs, no way I could have done that with 1 golf bag.
None of my gear was damaged, I have used it all since the trip.
The Ion Core bag retails for around $195 from Ion stockists.
