Easier than an M50 filter to take on and off. You can do it with one hand if it’s on your face easily.

I use these filters on my SOTR mask when shooting suppressed in an enclosed environment and they work extremely well!

They work well in my testing. The head-strap creates a nice seal. The helmet strap is more finicky and harder to get the seal. I bought one for my wife and the one-size-fits-all did not fit her. My experience buying from HCC was excellent.

The product speaks for itself because it’s gentex. Lightweight, portable, easy to clean and fits flawlessly. I would much rather comment on how the customer service for HCC Tactical is. Back in March, I called and spoke with Mike who told Me they were back ordered till June. I went ahead and placed my order and once they got in stock, the SOTR was on my door within days. Mike was very transparent and respectful. Will definitely order more gear from HCC Tactical. Keep up the great work!
