OC Tactical has made two updates to their facemasks. First, they are now including a disposable PM2.5 filter insert with each mask in addition to the included disposable fiber filter insert. This addition comes with a very slight price increase ($7.00, up from $6.25). Second, the mask is now available in Multicam in addition to the previously available Tiger Stripe and Desert Tiger Stripe options.
I purchased a number of these when they were initially available and I am very pleased with them. The ear bands in particular are extremely comfortable and the ability to insert disposable filter media is a nice feature. I also find them to be quite affordable.
