Perfect for a backpack or a purse
Color: Upgrade-black, Size: 14 Inch, Color: Upgrade-black, Size: 14 Inch
I love this black backpack. It has gold zippers and brown accents and it has a pocket in the front two on the side three inside and a pocket on the back of the laptop pocket. I have a disability and have to carry extra stuff so this is a perfect size for me to wear in my back every day. It’s black nylon so it should stay clean. I tend to drop things. I think this will be great, but even without a disability, this is a great backpack. It’s so cute.

Perfect day bag!
Color: Upgrade-black, Size: 15.6 Inch
Super convenient and lightweight. I used it for two back-to-back conferences last week and it was PERFECT for what I needed to tote along all day. Fits my regular sized computer (15-16 inch) and even held my water bottle (which is larger than a regular plastic water bottle).

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.
