As a veteran traveller, I expect a lot from my luggage and this little underseater delivers. Not only does it have a sleeve for your laptop, but also the side zipper pockets so necessary to carry a water bottle or snacks. There is a removable insert for personal products but I find that it takes up too much room and leave it out when I pack. Depending upon your clothing choice and packing style, you can easily pack for a 3-day trip. Because it is fairly lightweight, I don’t think twice about grabbing it when planning even just an overnight. I would recommend this product without hesitation.
