Convertible suitcase/backpack

Bags that do double duty are so valuable.
I have a soft-bodied rolling suitcase that has hidden backpack straps in it, and it's the bag I use almost every time I go anywhere.

This bag looks similar to what I have (maybe a little stiffer fabric) but is versatile and has a really good price. It doesn't have wheels, but you can carry it by the side like a duffel or with backpack straps.

Having separate outside pockets is also really important- I like to keep my underwear and makeup and hair stuff separate, and then use the extra pocket for laundry on the way home so it doesn't contaminate my clean stuff.
