I don't think it's a development issue, it's an education issue. There are plenty of masks out there that fit well and are meant to be worn for extended periods of time, be it in a medical environment or a trades environment. The problem is people who didn't wear the masks pre pandemic don't necessarily know how to properly fit a mask or how to identify product lines that are of higher quality and better for long term wear. OSHA has a lot of great videos on this topic and has regularly published on it for decades, but we've done a poor job disseminating it to the general public.
