The Saddlebag is a soft side cut and sew accessory, designed to make your on board trip more enjoyable. It is the perfect accessory to organize your personal items like tickets, jacket, overcoat, umbrella, reading materials, music, snacks, headphones, etc. and make them easy to get at. It has a special reinforced external loop that slides over the extension handle and lets the Saddlebag ride piggyback on top of your Porter Case. Roll them down the aisle of the airplane and when you get to your seat, slide off the Saddlebag off and put it under the seat in front of you. Then place the hard side Porter Case up into the overhead compartment. It has 400 denier double wall construction with light padding in between. There is a zippered main storage compartment 4 x 21 x 14-inch wide, a smaller outside pouch with a Velcro security flap that will hold legal size papers, a third smaller open pouch for quick in and out items, embroidered Logo, and an adjustable shoulder strap with grip. The perfect travel companion for easy access to those items you always want during your flight.
