All it takes is a microwave, water, and some paper towels. AIRWAAV HIIT requires 60 seconds and AIRWAAV END requires 90 seconds. Fitting instructions are included with each purchase and we have a fitting video on YouTube.
AIRWAAV is made with a patented material called vistamaxx. This material will shrink 24 hours after the initial molding to provide an even better fit.
If for some reason you notice the molding is incorrect, you can remold your AIRWAAV using the same process.
