i-MASK is the player’s first choice because it has eliminated all the disadvantages of competitive products like: fogging, hazing, nose discomfort and restricted peripheral vision. The visor can be worn over glasses, supporting them & helping to protect the spectacles from impact on lenses or frames.The i-MASK visor does not have a frame around the visor. You look more as though you’re wearing a sweatband than eyewear. There is virtually no vision restriction. Because the i-MASK visor weighs so little, you’re likely to forget you’re wearing it.You can buy replacements for all parts of the i-MASK visor so you don’t have to buy a whole new unit if one part is damaged or lost.
