One mask. Two temperatures.
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.
How the color shift works
The fabric is woven with a thermochromic pigment that responds to temperature in real time — no batteries, no electronics.
Put it on cold
Fresh out of the box or off a cold ride, the mask sits at its base color.
Your heat activates it
Body heat and breath warm the fabric, triggering the pigment to shift.
Watch it change
Over a few minutes the mask settles into its warm-state color — then back again as it cools.
Built for the outdoors
Soft thermal fleece lining, breathable nylon shell, and a fit that layers cleanly under a helmet or hood.

Common questions
How long does the color change take?+
A few minutes of wear is usually enough for the fabric to reach its warm-state color, depending on outside temperature.
Does it fit under a helmet?+
Yes — the fleece lining is thin enough to layer cleanly under a ski or bike helmet.
What size should I order?+
Most adults fit the L size (head circumference up to 60cm). The S size suits smaller heads or a snugger fit.
