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.
