Polartec Delta

The fabric innovators at Polartec did it again with the creation of Delta, a cooling fabric that utilizes the body's natural cooling process - sweat.  Unlike traditional wicking fabrics that move moisture vapour for rapid evaporation, Delta works harder and smarter to keep the wearer cool by elevating touch points for increased airflow, optimizing moisture dispersal and reducing wet-cling against the skin.  By using both hydrophobic and hydrophilic yarns, Delta regulates dry times and allows better breathability when it's wet.  The patent-pending radiating knit structures keep you cooler in hot conditions by increasing airflow to dissipate heat.  This technology makes this fabric NOT suitable for winter base layers.  To learn more about evaporative cooling, please check out our blog article!

What are some of the Benefits of Delta?

Polartec Delta comes in many different styles but all styles have the following features in common:

• Cool to the touch (once damp)
• Regulated drying (dries more slowly than quick-drying fabrics to promote evaporative cooling)
• Reduced cling when wet
• Highly breathable
• Superior Wicking
• Odour control (*in some styles only, denoted with "OR")

We carry a few different styles of Delta. Please see the Specs and Features tab below for details on each one. Some styles offer sun protection and their UPF rating will be noted.  

What can you make with Delta?

Delta is most often used for tops.  It can be used to create and entire top or it can be used in conjunction with other fabrics.
