XUONII Accordion Backpack is a fully waterproof and size adjustable backpack tailored to the needs of the user.
The technicalities of this product aims to demonstrate the unlimited and limited requirements of space and volume through a travel accessory such as the backpack. It can both expand to accommodate large items and compress to keep the backpack streamlined to be easily stored away when not in use .
Following the design philosophy of 'Space-saving', the backpack is created in one piece 'mono-material', using Bio-TPU or similar recyclable thermoplastic elastomers with different levels of hardness. This manufacturing strategy not only makes production extremely cost effective, is in stark contrast to other similar products on the market today, which are multi-material harder to recycle and expensive to manufacture.
