Samsonite's F'Lite GT 31" Upright is constructed of a polypropylene hardside shell. The shell is very lightweight yet durable. Multi-stage monotube handle has different height settings and makes steering easy. Top and side carry handles helps make carrying easy when you cannot roll the piece. Large, smooth rolling wheels add enhanced mobility. Divider panel with zippered pocket and elastic cross straps holds contents relatively in their place. Mounted Travel Sentry combination lock provides much needed security.
