TherMax® Vacuum Insulation
TherMax vacuum insulation virtually eliminates temperature change by creating an airless vacuum space between two stainless steel walls. The result is an insulation layer that performs better than any other. A superior insulated container you can depend on to keep your beverages hotter, cooler, fresher longer.

Insulation Excellence Times 2
The superior temperature retention performance provided by IsoTec™ is achieved by using a multi-layered insulation structure consisting of a layer of dense, closed cell polyethylene foam positioned between a rugged outer layer of textile and an additional moisture repellent heat-sealed PEVA lining. Using more layers provides better insulation and better cold retention. IsoTec Ultra features a layer of 12 mm thick closed cell polyethylene foam surrounded by polyfill for ultimate insulation.
