I keep meaning to make a video of this bag, it's that great! I did a lot of research because I wanted to avoid a checked bag and still needed to carry on clothes for a week - which isn't normally an issue but I am a plus sized woman - we just have bigger clothes!  Without the expansion zipper open, I fit: 7 pair of shorts/capris, 6 shirts, 2 pair of size 10 shoes, underwear, jammies, 3 bras, 2 bathing suits, 1 towel, toiletries (the forehead compartment was perfect for TSA access), a large curling iron, brush, and more that I can't remember...plus some gifts when I returned home. The straps inside kept everything in place and the compression straps made sure that the bag still fit in the overhead!  This bag felt durable and didn't show any distress after the trip.  I used the backpack straps while carrying it and chose to leave the shoulder strap at home. The soft handles were excellent for tossing it around during screening and loading.  Do I wish it had wheels - yeah, but getting the bag with wheels wasn't worth losing the couple inches in volume.  Please feel free to ask me questions about it!  PS: the color is beautiful!
