Thermolite Jacket

The Thermolite Jacket has been specifically designed to balance maximum insulation with comfort and weather resistance whilst keeping it lightweight. Our most popular static insulation jacket, ideal for use in extremely cold climates, when you’re likely to be static for an extended period of time. Highly packable, the Thermolite Jacket compactly stores in its own stuff bag, allowing you to have a high insulation layer ready to go for when you slow down on the hill or for when you’re back around camp during plummeting temperatures.

*The V1 Version features an advanced thermal reflective lining which is designed to reflect heat back into the body when worn during static conditions in colder alpine conditions. We recommend wearing this with an appropriate baselayer. If worn next-to-skin and in high activity, some claminess may occur.
