So versitile. So glad I bought two!  I use one as a tote at the store to buy groceries, then convert it to a backpack to wear as I ride my bike home.  The other I use as a dance bag.  Straps are padded and comfortable.  Mesh panel allows contents ventilation, as well ventilation against my back in back-pack mode. Holds pleanty of stuff.  Flat bottom allows bag to stand as you load/unload it.  Top opening opens up nice and wide to easy access to everything inside.  Qualilty is better than I expected for the price.  Thick fabric, durable stitching.
