Problue Frameless Mask
The Problue Frameless Mask is a lightweight, single lens dive mask. Featuring a double feather-edge in its design, this dive mask is very comfortable to wear and fits well on most faces.
Designed to be frameless and low volume, this dive mask offers a wide field of vision and is very easy to clear. On top of that, the silicone skirt features an unique buckle system that swivels with facial movements. This helps to absorb shocks and prevent buckle breakage when mask is bumped. The buckles also come with push buttons which allows you to easily make adjustments to the straps.
One more cool feature to note about this mask is that it comes with an anti-fog technology!
