these are probably at least 1/2 size larger and they are much looser fitting. This has also helped organize my closet much better. Having only one charger and two cables to carry around saves weight and space in your everyday carry bag. I actually have the 7510-109 version and have been looking to get another for my wife. Edit: adding that 5th star as I continue to be impressed. Its light, easy to transport, and very easy to assemble. Upon unboxing the item one of the two zippers was broken however, we didn?t have the time to return and replace the item so we made it work with the one zipper. Great for on the go if the fact that they dont fold is not an issue. Last but not least they finally, FIIIINNNAALLLLYYYY made it possible to fold the damn things up for easy storage/transport. The phone calls are clear.
