ABOUT VIETNAM ERA USARMY UNIFORMS:
WHILE THE US ARMY UNIFORMS OF THE 1950s WEREDOMINATED BY THE NEED FOR COLD WEATHER PROTECTION IN KOREA, THE UNIFORMS OF THE1960s AND 1970s EVOLVED TO MEET THE REQUIREMENTS OF THE WAR IN VIETNAM.
FOR FIELD USE, THE FATIGUE CAPS OF WW II ANDTHE 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 MODIFIEDIN 1969. THE FINAL ITERATION OF THEBASEBALL 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 THEWAS 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 INCREASEDMANUFACTURING EFFICIENCIES AND MADE THE CAP BETTER SUITED FOR WEAR w/ HEADSETSAND EARPHONE STYLE HEARING PROTECTION.
TO DETERMINE HAT SIZE:
MEASURING FOR YOUR HEAD SIZE IS A BIT ART ANDA BIT SCIENCE. YOU CAN USE A TAPEMEASURE, OR A LENGTH OF STRING THAT YOU WILL HAVE TO COMPARE TO A TAPE MEASURETO DETERMINE THE LENGTH. PLACE THESTRING OR TAPE AROUND YOUR HEAD ABOUT 1/8" ABOVE YOUR EAR, ACROSS THEMID-FOREHEAD, COMPLETELY CIRCLING YOUR HEAD.HOLD THE TAPE FIRMLY, BUT NOT TOO TIGHTLY. BASICALLY, YOU NEED TO MEASURE YOUR HEADEXACTLY WHERE THE HAT WILL SIT. IF YOURMEASUREMENT FALLS BETWEEN SIZES, IT’S A GOOD IDEA TO CHOOSE THE NEXT LARGESTSIZE.
ANOTHER, POSSIBLY MORE VALID METHOD TODETERMINE HAT SIZE IS TO TRY ON A HAT AND CHECK THE SIZE. IF YOU DON'T OWN A HAT, THEN TRY ON SOMERANDOM HATS NEXT TIME YOU ARE OUT SHOPPING.SIZES, EVEN THOUGH THEY DO VARY DEPENDING ON THE HAT MAKER, ARE SUPPOSEDTO BE UNIVERSAL. YOU MAY REFER TO THESIZING CHART BELOW IF YOU NEED TO CONVERT A MEDIUM TO AN ACTUAL HAT SIZE.
PLEASE UNDERSTAND THAT HATS ARE NOT UNLIKEOTHER APPAREL, IN THAT, SIZE CAN VARY SOMEWHAT FROM ONE MANUFACTURER TO ANOTHEROR EVEN IN DIFFERENT STYLES AND LINES FROM THE SAME BRAND. BECAUSE OF THIS WE CANNOT GUARANTEE THAT FOLLOWINGTHESE INSTRUCTIONS WILL RESULT IN A PERFECT FIT.
