What sizes do Polar Skin Ice Sheets come in?

Standard Polar Skin Ice Sheets measure 36 inches × 30 inches each. They are available in Single Pack (ZZ-0668, one sheet), Double Pack (ZZ-0669, two sheets), and Triple Pack (ZZ-0755, three sheets) configurations. A Polar Skin Ice Sheet Large version (ZZ-0758) is also available in a 36"×60" size for full-body coverage. Two Triple Packs are required to form a complete Polar Skin Comprehensive Cooling System.

Do Polar Skin Ice Sheets need to be frozen before use?

Yes. Polar Skin Ice Sheets are pre-saturated with ArcticAqua and should be stored in a cooler with ice before use. The ArcticAqua solution remains pliable and non-rigid below 0°F, so sheets stay conformable even at freezing temperatures. They react to elevated body temperature to promote evaporative cooling on contact, meaning they work most effectively when chilled — but the moisture-permeable mesh also enables evaporative cooling at ambient temperatures.

How do Polar Skin Ice Sheets differ from standard cold packs or wet sheets?

Standard wet sheets provide only evaporative cooling. Cold packs provide only conduction. Polar Skin Ice Sheets deliver all three mechanisms simultaneously: conduction (cold contact from ArcticAqua-saturated mesh), evaporation (moisture vapor release through the 518 CF/M permeable Mini-Mesh fabric), and convection (air movement through the open mesh structure). The hydrofunctional polymer treatment provides 350% greater liquid retention than standard fabric, sustaining the cooling effect significantly longer than ordinary methods.

Are Polar Skin Ice Sheets single-use or reusable?

Polar Skin Ice Sheets are designed as single-patient-use items. They are sealed in foil pouches that preserve the ArcticAqua saturation. Once opened and deployed, the sheet should be used for one patient treatment. The foil packaging also enables easy inventory management and extended shelf life as part of a pre-staged heat stroke treatment kit.

Do Polar Skin Ice Sheets have a military NSN?

Yes. The Polar Skin Ice Sheet Single Pack (ZZ-0668) is assigned NSN 6532-01-653-6054, indicating it has been through U.S. military procurement channels and meets Department of Defense supply standards. This NSN makes Polar Skin Ice Sheets procurable through military logistics systems for units that require NSN-sourced medical supplies.
