After wearing both of my RZ masks periodically over a couple months, I really didn't like the way either one fit, so I decided to improve the design. Watch me demonstrate four different ways you can modify the M2 or M2.5 masks for a better fit and seal. I put links below to some of the materials you might need, depending on which approach you select.
These modifications range from extremely easy and free, to reasonably easy and inexpensive. I recommend trying one of the temporary approaches before committing to something permanent. This is a long video because I thought it might help some people to see the whole process of sewing the modifications, but it's broken in to chapters for easier viewing.
This is the original unboxing-and-review:
