IsoTec™ Insulation
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.

BPA Free Why it matters

Bisphenol A

Bisphenol A (BPA) is a controversial chemical that can be found in the lining of food cans, certain water bottles and more. Some researchers have linked the hormone-mimicking chemical to a host of issues including behavioral and developmental effects in kids. Thermos plays it safe, and has made a commitment to only manufacture products that are BPA-free.
