TheCG634 is the maincombat helmet of theCanadian Armed Forces. It was introduced in 1997 and is based on the FrenchGallet TC-3 helmet.[1] The helmet has protection equal to anNIJ Level 3a rating, being able to stop a shot from a.357 Magnum.[2]
The Canadian military sought a replacement for the steelM1 helmet in the 1980s. In 1984 it trialled the BritishMk. 6, the AmericanPASGT and the Israeli OR402 composite helmets to determine the best characteristics of form, fit and ballistic protection. A concept design was developed and the Barrday Co. ofCambridge, Ontario, received a contract to produce over 2,000 Spectra helmets between 1988 and 1990 for ballistic, engineering and user trials. While the Barrday helmet performed well ballistically, field trials identified significant shortcomings.
The Barrday contract was scrapped and the search for a new helmet resumed in late 1992. After testing a number of European off-the-shelf designs the process was completed in May 1996 and a contract to produce 60,000 helmets was issued to the French company Gallet, which produced the TC-3 helmet and its variants for the French, Danish and Austrian armies. From 1997 to 2004 the CG634 was manufactured by Gallet Sécurité Internationale Inc inSaint-Romuald, Quebec. Subsequent contracts were placed withMSA, which bought Gallet in 2002.[3]
Revision Military Inc (now rebranded as Galvion inc as of 2019 as they sold the eyewear branch along with the name) purchased the MSA Gallet factory that produced CG634 helmets fromMine Safety Appliances in 2012. They were awarded contracts to produce replacement parts and refurbish CG634 helmet shells during 2015-2020.
The CG634 is made ofaramid (Kevlar) and has a minimumv50 of 634 m/s (compared to the PASGT's 610 m/s). It mates a modified French design, based on the PASGT, but adapted for compatibility with Canadian equipment (head-set, respirator, vision devices and armoured vest). The suspension system combines a thick foam trauma liner with a rubber and nylon webbing suspension based on the French Mle-78 (Gallet TC-3). The CG634 has a three-point chinstrap with flip-down adjustment pieces.[4] The CG634 was produced in 3 colours: green, black, and orange.
The CG634 has a somewhat similar shape and is sometimes mistaken for the laterUnited States Army'sMICH TC-2000 Combat Helmet. The MICH uses a foam padding system in its ground-combat helmet instead of webbing. The only pad system approved for use in combat is manufactured by Team Wendy and supplied by National Industries for the Blind.[5] These pads may also be used with the CG634.
When necessary, anight vision goggle mount is issued. The mount consists of a green metal bracket that hooks over the front of the helmet and the mount, which is screwed into it. There is a strap that loops through the mount and connects to a large ring, which is usually on the top of the helmet and two more straps secure the mount to the back of the helmet.[1] The mount is compatible withAN/PVS-7 andAN/PVS-14 night vision systems.[citation needed]
The CG634 helmet can be worn with a Camoflauge Cover in:CADPAT Temperate Woodland, Arid Regions, Artic/Winter Operations (CADPAT and plain white), UN Blue, UN Blue with markings, and black. As well as a Scrim Net and Camouflage Band.
The CG634 is scheduled to be replaced with the new CM735 combat helmet fromMorgan Advanced Materials, which is based on their full-cut LASA AC914 for combat operations and the high-cut LASA AC915 for special operations.[6] As of 2019[update] NP Aerospace was due to supply the helmet over seven years.[7]

In 2014 the Canadian military sought an interim replacement for the CG634 that would be the same shape as the CG634 helmet (minus the visor/lip), have interchangeable parts, and be lighter and have more ballistic resistance than the CG634. Morgan Advanced Materials won the contract for the Second Generation CG634 helmets after the LASA AC914 helmet designed using DSM Dyneema'sUHMWPE ballistic fibre went through trials and was accepted. The CM735 helmet entered production in 2015 and began to be issued in 2016.
In 2019 NP Aerospace (formerly a part of Morgan Advanced Materials as NP Aerospace Ltd) was awarded a contract to produce CM735 helmets over 7 years, however helmet production has ended as of 2022.
Beginning in 2023 after trials in 2022, the Batlskin Caiman helmet under the designation Helmet High Cut Ground Troop's from Galvion Inc. is being issued in limited quantities to some units to replace CG634 and CM735 helmets as part of the Dismounted Infantry Capability Enhancement program.
The most noticeable difference between the CG634 and CM735 helmet is the lack of a visor/lip on the front of the CM735.
