CLOSE-BODY COOLING PATH
Clear tubing runs across the upper back to keep circulating water close to a broad contact area. A fitted garment helps the cooling path stay near the wearer without bulky ice packs.

COMPONENTTwo transparent 6 mm water lines connect the garment to a compact 13 × 7.8 cm cooling unit. The unit sits on a slim 5 cm waist belt, while the compatible power bank remains inside the concealed pocket.
Heat can slow work, shorten rides and end long days early. FROSTSKIN combines a close-fitting cooling garment with a compact thermoelectric unit that lowers and circulates water temperature while you move.
Clear tubing runs across the upper back to keep circulating water close to a broad contact area. A fitted garment helps the cooling path stay near the wearer without bulky ice packs.
A solid-state thermoelectric chip lowers the circulating-water temperature while a fan releases heat from the unit. The system uses no refrigerant and requires no pre-frozen inserts.
A micro pump moves water through the garment circuit and two transparent 6 mm lines. Keep the lines free from sharp bends so the loop can circulate normally.
The approximately 13 × 7.8 cm cooling unit mounts to a slim 5 cm waist belt. The compatible power source stays in a separate belt pocket for a balanced, hands-free setup.
Connect a compatible power source to the cooling unit's USB-C (Type-C) port. There is no on/off switch; the system starts automatically when connected to power. Disconnect the power source to stop.
Xiaomi is included by default: approximately 1 hour of operation. Upgrade the included bank to UGREEN for +$10: approximately 2 hours. Spare batteries are sold separately. Actual runtime varies with operating conditions.
In prototype testing at 40°C / 104°F ambient temperature, circulating water measured approximately 28°C / 82°F. This is a water-temperature result, not a body-temperature claim.
Disconnect the cooling unit and power bank. Leave all sewn-in water tubing in the garment; do not remove or pull it. Keep electronic hardware dry and air-dry fully.
There is no on/off switch: compatible power starts the system automatically and unplugging stops it. Hand wash the garment only, keep the sewn-in water tubing installed, and never wash or submerge the cooling unit or power bank.
Runtime and cooling performance vary with ambient temperature, garment fit, airflow, power source and operating conditions. FROSTSKIN is not a medical device.
