This bag is definitely interesting. It’s pretty much an identical version of the the Subterra with rollers, but instead has hidden straps to be used as a back pack. This will be used for non-flight travel since it’s too big to stow under the seat and wouldn’t be practical to lug from gate to gate at an airport. I like the design and style of these bags, bought this during the 25% off sale, otherwise wouldn’t necessarily need it. It does include a really slick computer/ipad bag which can be carried separately, it’s like a bonus bag.
