Polartec Power Stretch™ Pro is a material tested where it matters most: by people who work outdoors. It transfers moisture efficiently from the inside to the outside, withstands heavy use and offers one of the best warmth-to-weight ratios in its class. These qualities have made Polartec Power Stretch™ Pro one of the favourite materials among the most demanding outdoor enthusiasts and professional users.
“On expedition-style ski treks, I like fleece made from Polartec Power Stretch Pro. It holds less moisture than wool and also resists the wind a little. So on warm days I can take my shell jacket off completely and ski in just the fleece.”


What kind of material is Polartec Power Stretch™ Pro?
Polartec Power Stretch™ Pro is 57% polyester, 33% polyamide and 10% elastane, with a fabric weight of 250 g/m². The material has two different surfaces: the inside is fleece that wicks moisture effectively, while the outside is durable polyester that resists pilling. This dual-surface construction makes the material both comfortable against the skin and durable in continuous use.
The material is very soft and offers four-way stretch, both horizontally and vertically. This ensures complete freedom of movement even during the most demanding training sessions and activities. Carefully constructed seams ensure a comfortable fit without pressure or chafing against the skin.
Where are Polartec Power Stretch™ Pro products designed and manufactured?
Polartec Power Stretch™ Pro products are designed and manufactured in Kärsämäki, Finland. The material uses advanced technology developed by the Polartec brand, specifically designed for high-intensity exercise and performance clothing.
