Correction - Here is a link to the entire patent APPLICATION. I’m a friggin patent attorney and I still typed it wrong.

Read the whole thing before you assume they are just trying to patent a simple bag.
Its just an application. Go and look at Figure 11-14 and I would bet that is where at least some of the purported novelty is.
So am I (other than the 'friggin' part ;-)...or perhaps not...). Folks tend to not understand that 1. it's so far only an application, and 2. the generic title may be "bag", but there are many ways to make a bag, and one can always come up with a novel and inventive way to make a *different* "bag". Be it materials, construction in detail, etc. And if it is patented, it does not stop others from making a bag of any other type.
