The Science Behind HydraVent hDc^TM

1. McDavid HydraVent hDc^TM starts with a patented process that permanently bonds hydrophilic (water-attracting) molecules to mid-weight and heavyweight synthetic fiber surfaces.  This ensures that the performance of HydraVent hDc^TM remains intact even after numerous washings unlike any other moisture transport technology currently available. (See care instructions for details.)
   
2. As you exercise, your body produces perspiration to cool itself.  In warm conditions, this perspiration condenses on your skin and builds up heat. (And discomfort.)
   
3. Moisture is pulled away from the skin by the wicking ability of HydraVent hDc^TM Your skin remains cooler and drier, and your body's temperature management system can do its job more effectively.
   
4. Once the fabric absorbs the moisture, it is spread rapidly across a broader surface area for faster evaporation.  It is this evaporation which draws heat out of the body.
   
5. Once the moisture is one molecule thick, HydraVent hDc^TM starts its drying process, allowing for a consistent and rapid moisture transport ability over a long use time.  McDavid HydraVent hDc^TM  evaporates moisture faster than any other fabric after the initial washings, including any modified cross-section fiber.
