The single lens, low-volume frameless Ghost mask offers a comfortable fit, a superb field of vision through a durable Ultra Clear lens, and a super-soft silicone skirt that blocks out light reflection – a huge plus for photographers. The mask strap has a push button release and an easy-adjustment lever for easy donning, doffing and length adjusting. The flexible easy-adjust buckles allow for a wide range of strap angles so you can achieve a good fit, plus they enable the mask to be folded flat for packing.
