Former Army Ranger Loves the CM-6M
I have ample experience wearing and training with US military gas masks including the M17 & M40 (both of which I have in my emergency kit). I wanted to try a full faceplate mask for improved visibility. I purchased the MIRA CM-6M mask prior to the NOV-24 elections - it was delivered quickly and fits great. I am amazed at the increased comfort and range of peripheral vision compared to the M17/M40. While I have not tested this mask in a gas chamber or any "real" event - I am confident it will be my 1st choice if needed.
