I got the red version of this bag the last time it was on Woot. It’s much higher quality than the picture makes it look.
Here’s an imgur album I put together so you can see the details more clearly.
The zippers are very high quality. The strap is adjustable and has a padded bit that you can move around for comfort. All the zipper pulls have a thick silicone Hello Kitty head on them. The bottom isn’t padded, so you’ll want to be careful dropping it on the floor with anything fragile (like a laptop) in it. The internal laptop sleeve is padded (including the bottom).
There are also two mesh pockets on the sides of the bag (they’re not too stretchy), and the main interior area completely zips closed, which is super nice when you live in a rainy area like I do.
Overall, it’s a really well-made and cute bag for the price. If you have a 15" laptop, measure it first!! My work laptop is a Lenovo ThinkPad W550s, and it’s just a little too big for the laptop sleeve, although it does fit in the main compartment.
