I purchased the 17” Pro in black. It is a beautiful color and well made. There are so many pockets, and the bag is big. Ironically, the overall interior space is limited. I purchased for purpose of using as a single travel bag for 2-3 night stays. The front designed pockets allow for thin items, cord organization and small items, but these pockets added bulk once filled impacting the width of the bag significantly. The interior also has many pockets, but I attempted to use this space for clothes, shoes, and toiletries. I did use packing cubes, but struggled to fit items. Once squeezing items into ever last bit of space in the bag, the shape of the bag was huge. This looked ridiculous on a small person. The 17” bag full did not fit under seats, although some reviews suggested it does, perhaps if it is not as full it may. The sizing is accurate on the site. Ultimately, the bag is a good bag for work or school or daily commutes, but I will not use this bag for travel with clothing. I wish I had known, so I could have the right size for commuter purpose. Recommendations for anyone considering this bag… purchase the appropriate size for computer and commuter materials. The bag may be good for commuting or as a supplemental travel bag. Consider other options of your desire is interior space. You
