This bag is very cheap but the $15 would be far better spent on some takeout Chinese food.
As I guess you would expect, cheap materials, very flimsy design, the strap is adjustable but not long enough for an adult over 6 feet tall.
All in all .. basically worthless. I threw it in a closet never to be used or looked at again. Not worth the trouble to send it back. This was an impulse purchase that just did not work out for me.
