Elastics need to flex and stretch without straining.
Polartec® Power Stretch® was developed to expand our base fabric's durability and range of motion. The majority of elastic base materials can stretch during movement, but lack the tensile strength to recover their original shape and become permanently damaged. By utilizing elastic fibers with enhanced resilience in our stretch construction we made a performance-fit base fabric that can handle the pressure of demanding physical activities.
Stretch fabrics need dependable strength properties to consistently recover their original form after being pushed and pulled during activity. If an elastic fabric structure is overstretched it becomes permanently damaged and loses the ability to regain its original shape and performance qualities.
This is why Polartec® Power Stretch® is engineered with tensile resilience as a key feature of its construction. The next-to-skin surface keeps you warm and dry through touch points that diffuse and evaporate vapor moisture in the outer layer. Reinforced elastic fibers ensure the fabric consistently rebounds after every stretch.
Polartec® Power Stretch® has the ability to retain warmth without restricting movement or agility during activities. The outer surface has a low-friction finish that reduces irritation when worn with other fabrics and increases overall abrasion resistance. The next-to-skin layer stays dry, breathable and comfortable by continuously transferring moisture vapor for rapid evaporation.
This versatility provides flexible support and warmth for reliable comfort in any fitness based activity. Polartec® Power Stretch® wicks moisture like a base material, but can handle direct exposure to the elements when necessary.
