this mask is alright, it sits comfortably on your face, especially if you have a larger head. however, despite what the description says it does not come with a thermal lens, and without one the double padding and larger size works against it and it fogs up almost immediately. on a brighter note the lens is enormous compared to other masks and the field of view is astonishing, when you are wearing the mask, and it isn't covered in a layer of your own face moisture, you can barely see the mask itself.
wide field of view
easy to switch the lens
doesn't come with thermal lens (despite what the ASGI description says)
Annex doesn't have spare lenses to take advantage of the quick change system
also as a side note, the mask came in a Valken tactical box, and says valken on the strap, so why in the world is it listed as Annex? c'mon ASGI must you be this confusing?
