HeatWave is a thermochromic balaclava that shifts color as your breath and body heat warm the fabric — cold-weather protection that actually reacts to you.
The fabric is woven with a thermochromic pigment that responds to temperature in real time — no batteries, no electronics.
Fresh out of the box or off a cold ride, the mask sits at its base color.
Body heat and breath warm the fabric, triggering the pigment to shift.
Over a few minutes the mask settles into its warm-state color — then back again as it cools.
Soft thermal fleece lining, breathable nylon shell, and a fit that layers cleanly under a helmet or hood.
Every colorway shifts the same way — this just sets the starting shade.
