Reposhing this item- this is a size XS/S! Too small for my 6’ tall frame ;) It’s a fantastic bag- leader in the market and generously handles everything you need as a light traveler in an international carry-on size! This pack has a built in guard you can zip over the backpack straps to use it as a duffle or to protect them if you want to check it at the airport. At the 40L size, it does not come with the additional daypack. However it can be purchased and attached easily to the front straps. Questions? Leave a comment below!
