Delta™

Cooling Fabric

Polartec® Delta™ was created so cooling fabric technologies could better utilize the body's natural cooling process — sweat.

Next-to-skin fabrics that target wicking and fast drying will keep moisture moving, but don't work towards actually cooling the body down. Delta™ works more efficiently by elevating touch-points for increased airflow, faster moisture dispersal, and reduced wet-cling.

About Delta™ Technology

Polartec® Delta™ features an innovative composition that regulates dry times and allows better breathability when wet.

Delta's specialized knit construction uses both hydrophobic and hydrophilic yarns for more advanced control of moisture dispersal. These patent-pending radiating knit structures keep you cooler in hot conditions by increasing airflow to dissipate heat.

Delta™ Q&A
A
Evaporative cooling is the single biggest way our bodies shed excess heat when we're hot. It's the reason why we sweat. As our sweat evaporates, latent heat from the skin's surface is removed. This yields a reduction in temperature on the skin surface. Polartec® Delta™ works with your body to amplify its natural cooling mechanisms.
A
Wet cling is when a fabric gets so saturated with moisture that it sticks to the body. It occurs when a fabric is at its maximum capacity for moisture uptake and cannot move moisture from inside to out quickly enough to keep the user dry.
A
This refers to the natural tendency of yarns to reject or accept water. Hydrophobic yarns do not absorb water; hydrophilic yarns will.
