Mine goes so kinky that it feels like it is pulling my skin off my face.
I’ve worked several jobs that require all forms of face/respirator masks. No shave means no seal means no work means unemployment.
Of course the worst thing was you couldn’t itch your nose 3 seconds after putting it on and until you left the work zone and then you could peel it off of your face!
The worst is sweat in the eyes you can’t break seal to wipe the stinking out and you can just run off the drill deck to a clean Air spot even if you could with one eye down no depth perception and spinning metal is a disaster waiting to happen. Zipper fracs are the worst we will be drilling a well head 50 feet from the prior well head that’s under a frac job so you have an active rig and a frac job onsite at the same time it’s absolute worst time.
