Updated - I included the original Cotopaxi tag on the bag. Like new and only used on one trip. I am 5'5" and this bag is too large for me. I love this bag and will be getting a smaller version! It comes with a separate shoulder strap if you want to carry it like a bag instead of a backpack, a colorful and indispensable rain cover, and you can hide the hip belt if needed. The rain cover was never used. Check out the Cotopaxi website for details about the bag: https://www.youtube.com/watch?v=jKW327m_vvs I had no problem bringing this as a carry-on on the domestic European flights. I did not travel with it in Asia or the US but suspect it will be ok for domestic flights as long as you stay within the weight limit.
