Purchased this bag to transport most of my gear to a Pacific Island wedding that I was attending and wished to carry-on most of my gear.
Dimensions are spot on for the great majority of airlines but the weight of the bag itself doesn't help. Very easy to load it up with 25kg or more, well & truly over what most airlines will accept for overhead luggage storage.
Bag comes with a wealth of internal dividers, once I had my gear arranged, I had plenty of divider materials left over.
I like the inbuilt lanyards and TSA approved locks.
The casters are well built and it rolls easily. The pull-out towing handle, although it appears to be quite weak, is more that sufficient.
Think-Tank have certainly put a lot of thought into the design and the quality of construction is outstanding.
I would certainly purchase additional Think-Tank products again if the need arose.
