The Thule Aion 28 L travel backpack is a versatile bag with expandable storage to increase its capacity from 28 litres to 32 litres. It also features a convenient divider to separate your everyday items from your sports gear while preventing odours, moisture and dirt from spreading throughout the rest of your bag. A buckle strap attachment system lets you attach items to the bag, and a pass-through panel lets you attach the backpack to rolling luggage for effortless travel through the airport. The top zippered pocket keeps your items easily accessible, while the internal zippered pocket can hold a phone, charger, and other small items while on the go.
