Thank you very much for the attached images.
After looking at the pictures I can assure you that you have an original Kata BAG,
I would like to explain the difference that you saw in the web images and the bag you own. In fact some time ago we did make an improvement in the DR shoulder straps and we added an additional stitches and improved the padding inside the strap.
The version that you are having is the new version (I can see it from the image you have sent me and also according to the lot # of your bag - which produced after we made the changes).
Please note that the pictures at our web site are not correct and shows the older version of the DR shoulder straps. We would like to thank you for bringing it to our attention , and we will take care of it soon.
