With every mask I have ever worn prior to this one, I equalize by pressing very gently in the area above the nostrils and at the intersection of face and nose on each side of the nose. Hardly any squeezing--just pressing gently in that area, the area that I take to be the nose pocket. There is ZERO access to this area on the Atomic Medium Frameless mask. It is completely blocked off.
I suppose that if you have a very prominent nose that extends well beyond the frameless frame (ie, beyond the lens) of this mask then you will have something to squeeze. But in this case you are pinching the tip of your nose--just as we do to indicate a foul odor. You are not accessing the nose pocket, which is further inside at the base of where the nose and face intersect. Most masks allow access to this space--and even boast about allowing access to this space. In theory, if not also in practice, when you press the nose pocket, you are blocking airflow down closer to the nasal passages and ears. So you don't need nearly as much air pressure in order to equalize. If you are squeezing the tip of your nose, then you need more air pressure build up before the ears equalize. I noticed this difference immediately on my dive in the Atomic Medium Frameless. I was ready to toss the mask into the garbage bin after the dive (PM me if you want the buy this mask--one dive on it only).
Otherwise, there is nothing wrong with this mask. Field of vision is exceptional. And I think the lens is superior to ordinary tempered glass. Skirt is of the firmer variety, which I like because it allows quicker and easier donning and doffing of the mask under water.
