Fewer, smarter design elements allow the frameless Essence to live up to its name. A Liquidskin silicone skirt delivers increased comfort by combining two types of the material one firmer for stability around the single lens and the second softer and more elastic for facial contact. The result is an excellent seal and a light, durable mask. The wide single lens fits close to the face for a low internal volume and easy clearing, and adjustable strap buckles mount directly onto the foldable silicone skirt for flexibility and compact storage.
