GULL ABEAM Basic Single-Lens Mask This model is supported by a wide range of divers as a basic single-lens mask for scuba diving and skin diving. This is a white x clear mask. (This color is no longer sold.) I purchased it several years ago and have used it a few times for skin diving. The clear silicone has yellowed, so please be aware of this before purchasing. *Please understand that this is a used item before purchasing. *Returns are not accepted.
