Airhole Hyper Colour Balaclava Purple Pink

Breathe into it and watch it change. The Hyper Hole is made in a heat activated colour change fabric, so it changes colour where it warms up, like where your breath hits it, then fades back as it cools. Black turns blue.

How it works: the colour change comes from thermochromic pigment, the same science behind the colour-change T-shirts of 1991. It sits in microscopic capsules, each holding a dye, a colour developer and a wax. While the wax is solid, the dye and developer stay together and show their colour. Warm breath melts the wax, the dye turns clear and only the blue is left. As it cools, the wax sets again and the black comes back.

It’s a full hinge balaclava for snowboarding and skiing. Laser-cut micro-airholes on the face panel let your breath out instead of up into your goggles, so your lenses stay clearer, and there’s no ring at the mouth.

The hinge gives you full face coverage, or wear it down under your chin. The shaped face panel sits flat under a helmet without bunching, so it doubles as a helmet liner.

The fabric wicks moisture away from your face and dries fast, and it’s white inside. On our warmth scale Hyper Hole is an Everyday fabric, for roughly 0 to −10°C, the same as Drytech.

Fabric: 92% polyester, 8% spandex. One size, fits heads 50–60 cm.
