Stage 3 / K2 Thermal Factoid #4 of 5: Provides Full Freedom of Movement
Flexible Material With a 3-Layer Design
The material is soft, supple and fairly thin. So it may surprise to learn that it’s actually comprised of three different layers that are heat-pressed together: an inner grid-thermal layer to trap body heat, a middle layer that’s water resistant, and an outer layer that blocks wind.
Importantly, all three layers allow for multi-directional stretch, which makes Stage 3 and K2 so form-fitting and comfortable without the discomfort of traditional compression gear.
The entire K2 Thermal shirt uses this material. Stage 3 is designed for use with body armor and the core material is different so you don’t overheat in your armor. The Stage 3 core material is a moisture-wicking, polyester/spandex blend that does not include the inner thermal-grid layer.
