Have done some vehicle extrication with this. The smaller size works well for getting into tighter places that a larger helmet would restrict. Also did some hazmat training with it on. The light weight made it easier to handle wearing the helmet for a few hours in a row. It ended up being a lot lighter than my old helmet.

I use this when directing traffic as a fire police

I got his helmet to replace an earlier one I had. I also decided to try goggles instead of the shield. So I cannot say a lot about that feature. I have gotten an Underwater Kinetics light and mount because I like hands free as much as possible. I have added a rubber strap for small wedges. I do not like a lot added to my helmet for weight. It makes it awkward getting used to. I will be using it mostly around our air/ rehab truck.

Used for structural firefighting and vehicle rescue operations. Small form factor is ok for vehicle operations but provides less protection in fire operations. Also is not designed well for larger heads.
