Seac USA Libera Full Face Snorkeling Mask

I bought this mask, and three of the smaller version of this same mask to take on vacation for some impromptu snorkeling. They were ver convenient in terms of breathing while surface skimming, stayed pretty clear and fog free, and worked for light snorkeling. However, none of us liked trying to go deeper because you can’t pop your ears with the big mask. Also, my husband, who used this specific mask, said it made his face hurt after about 15 minutes. But, if you want a solid, easy to use surface mask, this is fantastic.
