HOT OUTSIDE.
COLD INSIDE.
Portable liquid cooling that moves with you.
HEAT IS
THE TERRAIN.
A close-to-body cooling circuit designed to move with the wearer.
STAY OUT

Active liquid cooling for long hours under open sun.

Active liquid cooling under protective equipment and riding layers.
REAL NUMBERS.
CLEAR LIMITS.
In a prototype test at 40°C / 104°F ambient temperature, circulating water measured approximately 28°C / 82°F — a 12°C / 22°F difference.
*Prototype water-temperature result, not body- or core-temperature reduction. Results vary by conditions.
THREE METHODS.
ONE CLEAR DIFFERENCE.
Fan clothing moves ambient air. Ice-pack vests store a limited amount of cold. FROSTSKIN actively lowers circulating-water temperature while you wear it.
FAN COOLING
CLOTHING
Moves surrounding air across the wearer. Simple and light, but it does not actively chill a circulating liquid.

ICE-PACK
VESTS
Starts cold and gradually warms during use. The packs require freezer time or replacement before the next cooling cycle.

FROSTSKIN
Thermoelectric hardware lowers the water temperature while a pump keeps it circulating through the garment.

FROSTSKIN prototype result: 40°C / 104°F ambient → approximately 28°C / 82°F circulating water. This is a water-temperature measurement, not a body-temperature claim.
THREE ACTS.
ONE LOOP.
The cooling hardware does the work. The garment keeps the cold close to the body.
- 01CHILL
A thermoelectric chip lowers the water temperature.
- 02MOVE
A micro pump circulates water through the back circuit.
- 03RELEASE
A fan exhausts heat away from the cooling unit.
Published figures describe circulating-water temperature, not body temperature.

FIVE COLORS.
ONE COOLING LOOP.
Five color previews rotate automatically. Subtle highlights move only inside the original tube shape; use the arrows, swipe or choose a swatch anytime.
Color is a visual preview. Final shade can vary with concentration, tubing and lighting.
ACTIVE COOLING.
BUILT TO MOVE.
A compact 13 × 7.8 cm cooling unit sits on a slim 5 cm waist belt. Two transparent 6 mm water lines connect the garment to the active cooling circuit, while the compatible power bank stays inside the concealed belt pocket.
TRAIL. WORK.
RIDE.
One active cooling platform, built for different bodies, different jobs and different ways of moving through the heat.
FISH THROUGH
THE HEAT.
Portable liquid cooling for long hours beyond the shoreline.
CONFIGURE YOUR
COOLING SYSTEM.
Every complete system includes one FROSTSKIN garment, the cooling unit, one compatible power bank and the USB-C-to-12V trigger cable. Individual components are also available separately.
KNOW THE
SYSTEM.
How does FROSTSKIN work?+
A thermoelectric cooling chip lowers the circulating-water temperature. A micro pump moves the water through the garment's back circuit, while a fan carries heat away from the cooling unit.
What does 12°C / 22°F mean?+
It is the measured difference between ambient temperature and circulating-water temperature in prototype testing: 40°C / 104°F ambient and 28°C / 82°F water. It is not a claim about core body temperature.
How long does the system run?+
The compatible FROSTSKIN power bank provides 2 hours of system runtime.
What is included with a cooling system?+
One selected FROSTSKIN garment, one portable cooling unit, one compatible USB-C PD power bank and one USB-C-to-12V trigger cable. A second power bank is optional for approximately two more hours of runtime (+$59).
How do I start and stop the system?+
The unit has no on/off switch. With the cable unplugged from the power bank, connect its 12V end to the cooling unit, then connect the USB-C end to a compatible USB-C PD power bank. Circulation starts automatically. Unplug the power source to stop.
How do I wash the garment?+
Hand wash only. Disconnect the cooling unit, trigger cable and power bank first. Leave the sewn-in water tubing in the garment; do not remove or pull it. Keep all electronic hardware dry and air-dry the garment fully before reconnecting.
When will my pre-order ship?+
Pre-orders are planned to ship within 30 days of purchase. We will email you if production or carrier conditions affect that estimate.
