Is it easy to take it down to take a sip of water then back up? Or do you need to remove it all the way to be able to take a drink?

Will this product warm the air prior to breathing?

How can this product prevent glasses fog-up if it doesn't have a tight contour fit around the bridge of the nose?

Can the piece over the bridge of the nose be bent for more seal (like dust mask)? Would help prevent glasses from fogging up.
