I have purchased Airback GO
I have purchased Airback GO for my short trips (3-4 days). It suits the purpose perfectly. The air system is handy although it doesn’t provide 50% more space. I would say, closer to 30% which is still a lot. The zips work well and seem sturdy. The backpack is comfortable. The only thing which doesn't work for me is the chest strap - it is too high, almost on my neck. The backpack fits under the airplane seat which is important for me. Looks well built and well thought through. Happy so far, next trips soon!
