Stylish, light (laptop, phone, notebook & pen) +
Color: Upgrade-apricot, Size: 15.6 Inch, Color: Upgrade-apricot, Size: 15.6 Inch
Perfect for work! I use it for laptop, charger and few items necessary at work. I have a few blocks to walk from parking to work location and this bag has replaced last backpack and purse. Much easier to carry one item than two or more. Plus, it has enough room if you need to use it for clothes and toiletries (road-trip) or carry-on.

I’m very happy with this backpack. The material feels sturdy and well-made, with a smooth finish that looks elegant and easy to clean. The size is perfect—not too big or bulky, but still spacious enough to carry everything I need. The stitching and zippers feel strong and reliable.
