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.

Size up
While I like the concept, it’s not true to size. I cut the tag off thinking this fit well, as I wear 38G in most HSIA bras, I found that throughout the day this rode up and gave me “quad-breast.” It also broke the skin on my back where the anti-slip rubber was on the band. It has potential, maybe if you size up with band and cup.
