Luggage Duffle Carry On Folding Bag by PACKNBUY is waterproof and lightweight and its simple and practical design is the latest miracle of Korean design because it folds away into its own little zippered carry pouch. This PACKNBUY folding bag was originally conceived and designed to be carried inside your suitcase (it only measures 19 x 14 cm / 7.41 x 5.46 inside the pouch), where it barely takes up any space, so you can bring it back from your travels full of souvenirs, purchases and, of course, duty free gifts for friends and family members. Travel Duffel Bag is great for going to gym, beach, shops, or even packing to school or picnics. The versatile tote can be widely used in our daily life. The bag is able to hold large quantities of items like clothes, blankets, towels, odds and ends, whatever you like. The sleeve can be slid on the luggage handle so there is no need to worry about whether the bag would fall from the luggage. It is more than a duffle kit; just feel free to use it. Constructed with nylon, it features light weight, water resistant and easy cleaning. Just because it is flat when not used, it can be stored in small space. Also awesome to carry for backpacking, trekking, camping and other outdoor activities. Have a nice day with Travel Duffel bags!
