What Is Tri Cool Technology?

Swig Life's Cooli and Packi coolers keep chilled with a combination of Tri-Cool insulation, plus ice! Our superior exterior construction, combined with closed-cell foam insulation and water-tight linings, are the foundation of Tri-Cool technology. Warm air is unable to penetrate inside your cooler because the exterior fabric, interior insulation, and air-tight zipper each act as a barrier.
