In a nutshell:
BAG1502N (9 racquet bag) has:
-Sturdier/soft touch/smooth material, tougher as well. Not canvas or rough abrasive material.
-Black plastic feet to prevent bag from touching floor (though it really kind of doesn't help much)
-A handle for you to hold the bag standing up, EX version does not have this. Think the handle for most backpacks at the top.
-Zips are sturdier and have a unique design compared to run-of-the-mill Yonex zipheads.
-IMO, most importantly, there is a divider in the middle compartment to seperate your belongings.
-EDIT: EX/SR versions have side pouches ONLY on ONE side of the bag, the other is just a YONEX wording. JP versions have side compartments on BOTH sides.
All these features are absent in EX/Sunrise models.
And the handle on top of a 1502N:
**just something I noticed: 6 racquet bags are "R" designated, 9 racs are "N" designated... my personal conclusion is because in Japanese, 6 is pronounced Roku, and 9 = Nana. So I guess... that makes sense to a certain extent?
