The quilted exterior is water resistant. The feel and texture reminds me of something between a canvas backpack and a track jacket. What I like about this is if anything gets on it, you can wipe it right off with a wet cloth and not worry about damaging the bag. The backpack straps are fully adjustable. Right above the straps is a triangular handle, referred by Reunion Blues as “the subway grip.”
The Aero series really blurs the line between a hardshell case and a gig bag. The problem with a hardshell case is the weight and bulkiness, while the problem with a gig bag is the lack of protection. Reunion Blues calls its method of protection Flexoskeleton technology. Unlike most empty gig bags, you cannot fold an Aero case in half.
