Separate Sack Suspensory

From the March 1922 issue of Physical Culture, as presented by the ever amazing Modern Mechanix blog, let me tell my fellow men three words that will change their lives forever. Ready?

Separate Sack Suspensory:

You can do the hardest work or play without strain, chafing or pinching if you wear a Separate Sack Suspensory. The S.S.S. has no irritating leg straps, no oppressive band on the sack, no scratching metal slides. It is made just as nature intended.

With the S.S.S. you always have a clean suspensory every morning. Each outfit has two sacks, you can clip one fast to the supporting straps while the other sack is cleaned.

That's it. Tramp, er ... carry on.
