Review (5/5): Lightweight, soft and fairly breathable...
I've been using these for years. I'll keep buying replacements as long as they make them! They're washable (I'd recommend on gentle/cold and in a lingerie bag) and mine usually last a couple of years with weekly washings. The elastic isnt' as sturdy as the mask itself, nor does it hold as snugly as I like, so I DIY and add some 1.5 or 2 inch elastic and hand sew it in place of what comes on the mask. However, the mask is the really good part that makes these a really good value and repeat buy for someone who's spent years working nights--and now can't sleep without one after switching to days!
