Retains its rectangular shape - love it!
"Excellent bag. I did a fair bit of research prior to purchasing. I love that the duffel is lightweight. It holds its shape - it's like a soft version of my wheelie suitcase! Colour is beautiful - dark lavender. Could even get away with using the handles as backpack straps if desperate. Very very pleased with my new duffel. Dominated Jetstar carry-on!"
