Has anyone used or seen one of these? I have only seen the equalizer Z2, Z4, and Z3. I am curious about whether the Equalizer one is as low volume as the Z2. Are the dimensions similar?

I used to have a Z2, but gave it away recently and need to get a new mask. I was thinking about getting a low-profile one window mask, but I want to find one with a relatively wide nose pocket (like the Ocean Masters).

Any input would be appreciated,
