Inso/Therm

Sprayway exclusive 100 polyester insulation material offering an extremely high warmth to weight ratio.

The Inso/Therm technology is an extension of our exo/therm family.

Following years of testing, we arrived with this Sprayway exclusive 100 polyester insulation material.

Insulated jackets work by trapping in warm air which is radiated by the wearer’s body, which then circulates and keeps the heat within the jacket.

Our Inso/Therm fabrics have varying degrees of insulation depending on the usage of the jacket:

20gm2 - Quite Warm
120gm2 - Extremely Warm

Very often we will "zone" our insulation, in order to provide extra insulation for more static areas of the body, keeping areas such as your arms, freer to move.
