The Engineering Behind Subzero

Most cooling products cool the air around you. Subzero cools you. Its 360° internal ventilation system works inside your clothing, bringing the feel of air conditioning wherever you go.

85% More Cooling Power

The 60-blade airflow engine and 5 directional outlets generate 85% more concentrated airflow than standard cooling devices, delivering the kind of full-body cooling that nothing you clip to your collar can match.

Cools Your Whole Body, Not Just Your Face

A 360° diffused airflow circulates inside your shirt, activating your body's natural cooling response. Heat is pulled away from your core, not just your skin. That is the difference between a cooling device and a personal AC.

Silent Enough to Wear Anywhere

At 36dB or less (quieter than a library) Subzero runs without drawing attention. Wear it at your desk, in class, on a commute, or at an outdoor event without anyone noticing.
