The Absolute Shoulder Strap, which combines a soft, durable neoprene pad with comfortable stretch backing, has a unique patented internal control-stretch system that has given it a well-earned reputation as the best shoulder strap available. Many customers have told us that they think the Absolute Shoulder Strap makes their heavy loads feel up to 50% lighter. When purchased with the Empire Builder and Zephyr briefcases, or by itself, the Absolute Strap comes with double-coated metal hardware that allows it to be used with any bag that has d-ring attachments for a shoulder strap.
