The RollFit Seal incorporates integrated stability panels for optimal sealing performance and stability all night long.
SIZING: Three Simplus RollFit Seal sizes are available -- Small, Medium & Large. All Simplus masks use a single frame size so any seal size can be used on any mask frame. If you would like to change the size of your mask, you can just purchase a different seal size and fit it to your existing mask frame.
USAGE: Simplus RollFit Full Face Seals are made up of two parts -- a silicone seal and an acrylic shell. The two parts CANNOT be separated.
