Perfect Small-ish Business Bag
Color: Apricot, Size: 14-Inch
I have been on the search for a small business bag, that can go on. top of my luggage as well as look nice in the office and at meetings. That will still hold all of my things while keeping me organized. So what fits, I can put my 12.9" iPad, with case and Magic Keyboard in the spot for a laptop. I can also put my 8x10 spiral bound planner, a notebook, mouse, small cable case, pencil case, water bottle and purse pouch with all my essentials. So my water bottle does not fit inside the side bottle pockets, so I do have to put it inside the bag it's self, but that's a no issue. The shoulder straps seem sturdy enough and the color beige/cream looks nice with my neutral wardrobe. Overall I'm happy with the purchase. We'll see how it travels over the next year as I have quite a bit of traveling and work do to offsite this year. j

Stylish, High-Quality Backpack. A Great Upgrade from My Usual Black Bags!
Color: Pinkish Grey, Size: 14-Inch
I’m really impressed with this backpack. I usually stick to black bags, but I decided to try something different, and I’m so glad I did. The color is beautiful—unique without being too loud—and adds a nice pop. The quality of the material feels top-notch. It’s sturdy yet lightweight, and the stitching and zippers seem very durable. Overall, this backpack feels well thought out in both design and function. Highly recommend if you’re looking for something professional, stylish, and practical.

Gorgeous, but some big downsides
Color: Pink-upgrade, Size: 14 Inch
I wanted to like this bag SO BADLY. I’ve owned other backpacks by this brand and they have never disappointed. This one though, was a close miss. The color is absolutely GORGEOUS and I almost kept it for that reason alone. However, two big things made me return it: 1) The inside is no longer padded. If you had purchased older Golf Supags backpacks, the interior had padding to help the backpack keep its shape and not slouch over on the floor. That’s gone, so this one does flop over a little. But the big deal breaker: 2) holy cannoli, these straps are WAY too long! On the shortest length, the backpack is still hanging almost halfway down my back. It looks weird, but it’s also not ergonomically good for your back. The actual strap part (with padding) is so far back that the thin seatbelt adjustable material is the only thing on my shoulders. Super awkward. I’m not necessarily a small person either, so I shudder to think what this would look like on someone more petite than me.
