I was very disappointed with this bag and I have returned it. From the picture it looks like there are wheels but there are no wheels. The colored bits look red but are actually a hideous orange.
Bought this for my boyfriend who travels daily for work, and flys often as well. He usually gas one, if not two laptops and an Ipad, and multiple chargers/cords. This was a great option bc he can wear it many ways, and it holds everything without being bulky. He is very happy with it!
