Dye I5 Foam Kit / mask foam to change (red)
Dye I5 mask foam to replace. Changing the foam will make your I5 feel like new again. Over time, sweat and paint residue accumulate in the foam, which makes the foam hard and reduces wearing comfort. In addition, the accumulation of bacteria can cause skin irritation. We therefore recommend simply replacing the mask foam every 3-6 months.
