As its name implies this is an oversize single lens mask, but with an unusually low volume.  The lens is angled towards your face for a dramatically increased range of vision, both peripheral and straight ahead.  The mask also allows lots of ambient light to enter, increasing vision underwater.  

The multiple position strap adjuster allows for a correct, snug fit on medium and larger faces, maintaining its seal even on faces with moustaches.  Tempered glass lens is super-clear, and IST’s renowned, high quality skirt and strap provide the ultimate in comfort.
