How long do the ice inserts stay cold?

At −18 °C the gel inserts sustain cold for about two hours; under 10 °C they hold for around four hours. The Vacuum Case extends that to six hours in transit.

Is this a medical device?

No — FRZN is performance swimwear and recovery gear, not a medical device. Cold and heat exposure stress the body; if you have a heart condition, high blood pressure, or are pregnant, check with a physician before starting a protocol.

How do the garments fit?

Cold Shorts and Plunge Trunk run true to EU size in XS–XL. Lumbar Towel and Vacuum Case are one-size; Field Robe comes in S/M and L/XL. If you're between sizes, size up for layering.

When will Edition 001 ship?
