Available exclusively from Hammacher Schlemmer, this is the only hardshell carry on that increases its capacity by 25%. Using patented technology, its expansion zipper extends the depth of the suitcase by 2 1/2", increasing the overall volume and creating ample space for unexpected cargo or souvenirs. Unlike similar expanding luggage constructed of thin polyester that leaves its contents at the mercy of baggage handlers, this model’s 1/4"-thick polycarbonate shell withstands the rigors of modern day travel. The generous interior is lined with rugged nylon, has a zippered mesh pocket and tie-down straps that keep contents neatly organized. Its eight 360° spinning wheels, 17" three-position locking telescoping handle, and two silicone-padded carrying handles make it easy to navigate through airport terminals. Slate. 21 1/4" H x 15" W x 9-11 1/2" D. (7 lbs.)
