ABOUT VIETNAM ERA US ARMY UNIFORMS:

WHILE THE US ARMY UNIFORMS OF THE 1950s WERE DOMINATED BY THE NEED FOR COLD WEATHER PROTECTION IN KOREA, THE UNIFORMS OF THE 1960s AND 1970s EVOLVED TO MEET THE REQUIREMENTS OF THE WAR IN VIETNAM. 

FOR FIELD USE, THE FATIGUE CAPS OF WW II AND THE 1950s WERE REPLACED BY AN OG-106 BASEBALL CAP STYLE WITH A NOMENCLATURE OF: CAP, FIELD (HOT WEATHER), SPECIFICATION DATED 9 JUNE 1961, AND LATER MODIFIED IN 1969.  THE FINAL ITERATION OF THE BASEBALL HAT STYLE CAP IN US ARMY UNIFORMS WAS THE EXAMPLE LISTED HERE.  THE CAP, HOT WEATHER, OLIVE GREEN 507 (OG-507) WAS AGAIN UPDATED WITH THE CURRENT 507 SHADE OF OLIVE GREEN AND THE WAS IMPROVED BY REMOVING THE BUTTON ON THE TOP OF THE HAT (INTERESTING FACTOID: THE BUTTON ON TOP OF BASEBALL HATS IS ACTUALLY CALLED A SQUATCHEE).  THE REMOVAL OF THE TOP BUTTON INCREASED MANUFACTURING EFFICIENCIES AND MADE THE CAP BETTER SUITED FOR WEAR w/ HEADSETS AND EARPHONE STYLE HEARING PROTECTION.

TO DETERMINE HAT SIZE:

MEASURING FOR YOUR HEAD SIZE IS A BIT ART AND A BIT SCIENCE.  YOU CAN USE A TAPE MEASURE, OR A LENGTH OF STRING THAT YOU WILL HAVE TO COMPARE TO A TAPE MEASURE TO DETERMINE THE LENGTH.  PLACE THE STRING OR TAPE AROUND YOUR HEAD ABOUT 1/8" ABOVE YOUR EAR, ACROSS THE MID-FOREHEAD, COMPLETELY CIRCLING YOUR HEAD.  HOLD THE TAPE FIRMLY, BUT NOT TOO TIGHTLY.  BASICALLY, YOU NEED TO MEASURE YOUR HEAD EXACTLY WHERE THE HAT WILL SIT.  IF YOUR MEASUREMENT FALLS BETWEEN SIZES, IT’S A GOOD IDEA TO CHOOSE THE NEXT LARGEST SIZE.

ANOTHER, POSSIBLY MORE VALID METHOD TO DETERMINE HAT SIZE IS TO TRY ON A HAT AND CHECK THE SIZE.  IF YOU DON'T OWN A HAT, THEN TRY ON SOME RANDOM HATS NEXT TIME YOU ARE OUT SHOPPING.  SIZES, EVEN THOUGH THEY DO VARY DEPENDING ON THE HAT MAKER, ARE SUPPOSED TO BE UNIVERSAL.  YOU MAY REFER TO THE SIZING CHART BELOW IF YOU NEED TO CONVERT A MEDIUM TO AN ACTUAL HAT SIZE.

PLEASE UNDERSTAND THAT HATS ARE NOT UNLIKE OTHER APPAREL, IN THAT, SIZE CAN VARY SOMEWHAT FROM ONE MANUFACTURER TO ANOTHER OR EVEN IN DIFFERENT STYLES AND LINES FROM THE SAME BRAND.  BECAUSE OF THIS WE CANNOT GUARANTEE THAT FOLLOWING THESE INSTRUCTIONS WILL RESULT IN A PERFECT FIT.
