Velcro blackstraps attached mask, this protector has a comfortable and secure fabric cover along the rim of the steel mesh portion. The mesh itself is plastic coated so as to resist weather and rusting. These masks are available in different colored and camo versions.
This Version 2 model goes a step further with two sets of straps at it does not just cover the mouth and nose but extends up past the law to cover the ears as well. The flexible nature of the mesh weave means that the mask is tightened such that it bends to conform and wrap around the curve of your head. The space and flex is probably sufficient to accommodate over the top of additional ear coverings like communications gear although that will depend on your comms equipment of course.
Furthermore, another upgrade over the version one is the addition of a fabric wrapped padded layer which allows for a tighter more comfortable fit around the jaw and chin.
Mesh masks allow breathing and talking through it unobstructed and as such are not as uncomfortable as solid masks nor do they have as much issues with fogging the eye protection or muffling your voice as much. That said, as a mesh mask it will stop broad objects but offer nothing for fine particulates so sand, dust, smoke and the like with drift through and high power BB strikes can result in BB fragments passing through the mesh (albeit it at a reduced velocity) but it has been tested up to and including repeated strikes at short range with 2 joule / 465fps weapons with no problem (again, no promises about fine particulates though).
The revised 3D cutting enhancement makes two small modifications at mildly greater cost, it adds additional stitching to the slightly different fabric cut to add a little surface texture to show its shape better. It also has a small (35 x 25mm) Velcro patch added on the lower jaw left side to allow the addition of small identification markers of your own choosing (not included).
Mesh masks offer one of the cheapest lower face protection options in Airsoft and offer advantages with breathing and communication but are otherwise not very suited for longer range use or when protection from environmental debris is a factor. When playing at shorter range and indoors with lower powered weapons however, the mesh mask can offer a very suitable option without hurting the wallet. Its also a nice choice for those of us who avoid lower face protection entirely due to fogging issues and so having one of these as the alternative to nothing at all can be all the more of a worthy option.
