Material Specs
Polyester & Elastane
This fabric blends polyester's durability, shape retention and moisture-wicking properties with elastane's flexibility and stretch. The result? A material with superior freedom of movement.
Balanced insulation and breathability
Our Warm layers offer an optimal balance between thermal insulation and active moisture management, neither function is sacrificed for the other. At the heart of the system, a Warm base layer is the right choice when cold protection and breathability are both required, from winter hiking and alpine skiing to cold-weather running. Best worn in a comfort range of -10°C to +5°C.
