Because I am also protecting my ears, vision, and airway I usually use my EYE MUFFS with a 3M classic 1/2 mask, and unless I am really in the chit, then I swap for my full face 3M mask for eyes and airway, and wear the ear muff portion of my eye muffs. Usually processing a lot of MDF or other similar "dusty" work is getting done is where I pull out the FF mask.

I can wear the usual Eye Muffs over my glasses, and with the easy 1/2 mask and puff filters for hours without thinking about them, Comfort, and no issues with them on. I get kinda claustro with the FF mask on after an hour or so, and wanna get it off. I've been known to walk out of the shop, up to the house, and forget to remove the safety stuff until my Wife points at her face, and shrugs, like hey dummazz you have too much stuff on..........
