This is intended for the Proflex X. It should work for any JT/Empire mask that used the Spectra lens quick change system. The JT Premise comes to mind, but I have not tested it with these yet.

The Proflex X was... Not great. It's stiffer and less comfortable than other versions. But it's far cheaper, the lens is infinitely easier to change, and every pro shop in existence will have a spectra lens for sale if yours gets ruined so I'd still argue it's one of the best masks you can get if you're on a budget (at the time I am posting this, who knows what the future holds).

I couldn't make them more flexible but I could make them more comfortable. These simply snap in behind the yellow piece, no modification required. The result is it no longer feels like an army of tiny fairy tail creatures is stabbing you repeatedly in the ears with their tiny swords. It takes the mask from barely tolerable for ten minutes to wearable for hours without making any modifications that affect safety.

Print out of TPU or other flexible material. Flat side down. Use supports.
