Most foldable bags follow the common concept of retaining the larger bag in a smaller bag cover. However, most of the cover tend to be square in shape. This travel bag introduces an interesting concept that does not deviate too far from the original idea of being a foldable bag but it does so using a circular cover that sealsÂ the foldable bag. This maximises the space to seal up the bag & it doesit efficiently with all the straps tucked in perfectly. It also has the hole used for the strap as a travel bag but can double as a method to hook it to another bag, saving additional storage space.
