Each person has a unique facial structure and every diver can potentially experience some level of discomfort or “pressure” while wearing a typical mask underwater. TUSA engineers wanted to solve these problems and spent several years analyzing mask fit, facial bone structure and mouth movement. The result is Freedom Technology, a set of revolutionary new mask features delivering superior fit, comfort and increased performance. Experience Freedom.
