Hollis - M1 Scuba Mask Black
- Product Review (submitted on 24 October 2015):
- This is a very well made mask, the high quality soft skirting make it easy to wear weather your diving or snorkeling. The masks lens has a low iron content, this produces a higher light transmittance and improved visibility. This is all helped again by the frame-less design giving the viewer larger range to see from.
