I got this with the Travelon shoulder strap.  This does the job, but I expected more, since this is suppose to be "THE" strap and is used by Tom Bihn luggage.  It absorbs the load, doesn't slip, and is stylish, but... The Travelon shoulder strap is better.  Who would of thunk it. It just isn't as stylish.  Who cares.  So, this strap is used for my messenger bag and the Travelon for my carry-on luggage.
