OK, so this mask is pretty legit looking. First off, it is rubber...it some says it's plastic, others say rubber - it's a thin rubber to help mold to your face/head.
You can breathe through it easily, and the mask mouth hole provides a nice damper to help you with your distorted Bane voice.
I give it 3 1/2 stars because it is one size fits all, and it's huge. I've tried clipping it and folding the sides over itself and using electrical tape to sinch it, but this doesn't work. My next step is to add velcro strips so I can put it on, then fold it over, velcro-ing it in place. I hope this does the trick and I'll update.
5 stars for looks and feel, 1 star for sizing and wearability.
