Guardian Skirt
The skirt of the Guardian FFM is made of
high grade (55-60 Shore A) liquid silicone
with some unique features that add to
its durability, comfort, and functionality.
Inside you will notice we have designed
the mask with a double-seal (Figure 3).
The double-seal makes the mask more
comfortable, but more importantly it
assists in sealing the mask (especially
at the temples—a common problem area
for sealing on most FFMs). This unique
design ensures the Guardian FFM will t
virtually every type face, small to large.
Practically eliminated is the “burping” at the temples found in other masks.
Dives of extended lengths are made more gratifying with a properly tting
mask. Additionally, the tabs to the buckles are designed to minimize any
damage resulting from improper donning of the mask. These tabs have
“button-holed” buckles—meaning if the head harness is pulled too hard
and out to the sides, the buckle will pull from the “button-hole.” While
this will require reassembling the buckle onto the skirt, it helps prevent
damage from occurring to the skirt. This is a common problem in other
masks. The buckles are extremely rugged and made of nylon instead of
metal, so they’re not prone to corrosion. If however, you break or lose one,
they are easy to replace.
