Most reviews on the XS Aviator don't actually ask for a strap, but rather for the installation of d-rings that would permit the use of a strap if needed/desired. I really don't think it would impact the price by that much. I had them added to one of mine by a cobbler for $ 9.00.

The hierarchy at Red Oxx is disinterested in making the mod (probably becuase it would impact sales on their higher end products). Despite the quality of the Red Oxx line, i have moved to another company that manufactures bags to the customer's specs. Cost is about the same and I get exactly what works for ME !

Red Oxx is now in my rear view mirror.
