Delta™

Polartec® Delta™ works with the body's natural cooling process dispersing perspiration across the skin for efficient cooling when hot. Specialized knit construction using both hydrophobic and hydrophilic yarns gives more advanced wicking control to reduce wet-cling and increase airflow breathability for evaporation to dissipate heat.

  • Stay cool, when the conditions are not.
  • Removes moisture to keep you in the moment, without distractions.
  • Made to enhance your body's own cooling process.
