🪖 The US M1 Helmet Chinstrap: A Quick Dating Guide
The M1 helmet's chin strap consists of two thin cotton canvas straps: a short one on the left with a "J" hook, and a long, adjustable one on the right with a buckle that receives this hook. They were originally sewn directly onto the helmet buckles, in olive drab #3, a light green shade.
🧵 The webbing weave
The original straps have a very specific weave: 11 visible rows of 3 threads each. This woven structure is an excellent indicator of authenticity and allows original chinstraps to be distinguished from modern reproductions, which are often more irregular or too finely woven.

🪖 Field tip
In combat, soldiers often attached the chinstrap to the back of the helmet rather than under the chin—but some straps were too short for this, a telling detail depending on the period of manufacture.
