This luggage collection is a smart choice inside and out. The large checked sized bag is equipped with a patented overweight indicator that is built in the side carry handle to let you know if your luggage weighs more than 48.5 lbs. It also features dual-density spinner wheels for superior mobility, a built-in TSA-accepted lock for optimal security and interior lining that is removable and washable so you can keep the inside of your bag fresh for your next getaway.
