I suppose this topic is for those individuals who are too broke to buy something better and have to make their equipment last longer, better. So, I'll start with my own attempt(s).
---I learned (from this forum) that if I cut the inside skirt off my mask (till there is no more skirt) then my mask volume reduces and will feel a lot better, though I do find myself tightening the mask more
--I realize that my esclapez have become too soft for me, so right now I'm in the process of epoxying .5" strips of shatter resistent acrylic on them. I haven't tested them yet though. I wanna work slow and tediously on this one.
So list your modifications if you have any, great or small. (remember for those wishing to use these ideas, proceed at YOUR OWN RISK)
