The 150 Frameless Mask uses a single tempered glass lens and low profile design to increase underwater field of vision by over 25%.  By not having a frame in the center of the mask coming over the nose, the field of vision is increased while still maintaining a low volume.  A premium quality double silicone face skirt comfortably seals the mask to nearly any size and shape face.  Textured panels on the outside of the nose pocket make gripping and pinching the nose for equalization easy, even with gloves.  Flexible mask strap buckles add to the comfort of the mask and allow it to be stowed without concern of breaking a buckle.
