I've been using one of these updated Transporter 130s for about 8 months now as part of product testing and general curiosity. So far it has tagged along to Peru and Ecuador for 3 weeks of high altitude mountaineering, on many a roadtrip stuffed with camping and climbing gear, and most recently to the Bugaboos in Canada for more climbing. This thing has transported ice axes and crampons on 3 international flights and not had an issue with durability, pretty stellar! There isn't much to it for organization, so it becomes a bit of a puzzle to pack if you have some irregularly shaped items - I haven't run into too many unsolvable pieces yet. The pack away shoulder straps have been huge, I can have it loaded with 70+ pounds of gear and still get across a few airport terminals without crumbling into the carpet. That also has allowed me to carry a smaller daypack on the front when I need to be moving. In Ecuador I left my packed Transporter outside in a light rainstorm that lasted 3 hours, all the contents were dry and the coated exterior beaded water like it was supposed to, nice. My gripe with these duffels is the zipper, as it can be tough to get going when the inside is full. It's a small gripe, as the zipper is definitely burly to help with durability, and the flap that covers the zipper path is there to keep things dry and clean.
