Scubapro Steel Comp Free Diving Mask
The Steel Comp Mask is a super low volume apnea/freediving mask. Features:
* Lowest possible volume double lens mask for minimal air use in equalising.
* Flat glass lens with scratch resistance guarantees clear, undistorted vision and long-term wear.
* Frameless design and soft skirt provides universal fit and sleek look.
* Rotating buckles with soft, flexible micro-adjustable strap for exact fit.
* Due to the frameless design the lenses can flex slightly, especially on narrower faces, and can cause some slight distortion.
