Currently I am in between purchasing new camouflage as my premade harness will no longer work. It's going to be a while still I can save up for a bunch of new gear. So I was derping around trying to get a price list when the game "The Division" came to mind. I remembered that most weekend game have a "civilian/contact" team and until I get tax returns and purchase new gear, I could essentially be a Division Agent.
The gas mask could be pretty much any kind as in game they switch based on whatever one you equip, but as I am running around I believe that this would be a good one. It stated on the website that the straps help lock down the mask, and a bottom vent helps direct air away from visors.
You can find the patch just about anywhere for really cheap.
And lastly the watch and beacon. For the watch I found this one for $5 on Amazon
And the beacon I was able to find someone had posted up a 3D model for print, but I could probably make one similar.
