Muji Boston Bag

The bag is designed to be highly packable. While exact folded dimensions aren't specified, its lightweight construction allows it to collapse into a small, flat profile that easily slides into a larger suitcase or backpack pocket.

Yes, with a 43-liter capacity, it meets standard carry-on size requirements for most airlines. However, keep in mind that it lacks the rigid structure of a standard suitcase, so it is best suited for clothing and soft items.

The fabric is treated to repel light rain and moisture, which is great for protecting your belongings while moving through terminals or light drizzles. It is not fully waterproof, so we wouldn't recommend submerging it or exposing it to heavy, prolonged downpours.

The bag features an integrated strap on the back panel that slides over the handle of your rolling luggage. This keeps the bag securely balanced on top of your suitcase, preventing it from sliding off while you navigate the airport.

This bag is intended as a secondary travel companion or an organizer, not as a primary piece of checked luggage. Because it is made of lightweight, collapsible polyester, it is not designed to withstand the rough handling typically associated with checked baggage.
