The M1 helmet is a U.S. Military combat helmet that was standard issue during WWII. It remained in service through 1985 until its eventual replacement came about in the form of the PASGT (Personnel Armor System for Ground Troops) helmet, which offered superior protection and ergonomics. It was originally developed in 1941 as a replacement for the M1917 helmet and was redesigned just prior to the Vietnam War. Today, the helmet has reached icon status, as its design has inspired helmets used by several foreign armed forces and they are now considered hard-to-find collectibles.

The M1 helmet has a unique design. Really, it is two separate helmets that combine to offer a "one-size-fits-all" sizing. It is made up of an outer shell, which is constructed from a single piece of non-magnetized steel, and a liner, which is a hardhat-style helmet that contains an adjustable suspension system. Since we are not concerned with the outer shell – very interesting in its own right – I will move on to the liner.

As noted, the liner has the look of an actual helmet. This is because it features a hardhat-style shell to which the adjustable suspension system is attached. This entire assembly is designed for a tight fit inside the outer shell of the M1 helmet. The importance of the liner, however, rests with the adjustable suspension system, which allows the wearer to adjust the sizing of the helmet for a proper fit. It consists of several components, all of which are beautifully reproduced for our U.S. M1 helmet liner.

The U.S. M1 helmet liner includes an adjustable suspension webbing system, which is adjusted by way of a cotton drawstring. This webbing is riveted to the inner shell and provides for a higher or lower seating of the helmet on the head of the wearer. There is also a leather sweatband that is clipped to the outer ring of suspension webbing. This sweatband is also adjustable and determines how tightly the helmet will fit around the head of the wearer. Additionally, there is a nape strap. This strap is made of the same material as the suspension webbing and exists to support the back of the head just above the nape of the neck. Like the suspension webbing, this component is riveted to the helmet. Finally, there is a leather chinstrap. This chinstrap is adjustable via a small metal clasp. The chinstrap was not often used as a traditional chinstrap due to safety concerns and because of the fact that the outer steel shell included a much more practical chinstrap. This interior chinstrap was often strapped across the brim of the outer shell in an effort to hold both components of the helmet together.

I cannot make it any clearer. The U.S. M1 helmet liner is truly a beautiful reproduction that is suitable for a number of different applications. If you are looking for an inexpensive replacement that is on par with the real thing, then look no further. Consider this liner for:

- Collections

- Reenactments

- Military ceremonies

- Costumes

- Replacement parts

- Much more...

Continued Military Use

The U.S. M1 helmet liner, while never intended for singular use, actually finds applications in the U.S. Military to this day. They are still used for training purposes by U.S. Navy SEALs candidates. They also find use in ceremonial units where they are often chromed.

Review by roguefox89
This liner was the perfect fit for my IDF M1 Paratrooper helmet. The original liner's fasteners and clips were rusted through and the webbing/sweatband were dry rotted. This replacement needed to have the band's clips tightened a bit, but that was easily remedied with some needle nose pliers.

Okay liner
Review by Nathan
When it arrived in the mail a rivet had snapped in half and the suspension had fallen out. It also did not fit in very well into my 1954 M1 Helmet like it said it would.

This helmet liner is made for the US M1 helmet, but will fit similar types such as the French Model 1950 and the Iraqi M80. Very high-quality replacement liner.

Review by Flo
I collect military helmets and the m1 helmet liners fit perfectly into my Iraqi m80 helmet, and liners for those are hard to find, so this was a great alternative.
