"Sweat Wicking Clothing" is clothing made with polyester microfiber formulations and blends designed so that sweat and water on your skin is sucked (wicked away), to the outer surface of the fabric, where it quickly evaporates. Normal fabrics
allow the sweat to be retained in the fabric.
The unique formulations of fiber allow the moisture in the fabric to evaporate. This
ability (unlike cotton clothes which collect and hold moisture), allow you to get warmer, take less time to dry, and carry less moisture weight.
How Do Moisture / Sweat Wicking Clothing Work?
The Fabric in Sweat Wicking Clothing pulls moisture away from the skin (a process originally used by diaper manufacturers). Today's Sweat wicking fabrics are constructed of water-repellent synthetic fibers, such as polyester, that are specially woven to create "sweat corridors" that promote capillary action (the same process plants
use to draw water to their extremities).
Once the mositure is wicked to the surface of the garment, air movemement and other factors enable your sweat to evaporate into the air.
How do I care for it? Why not use fabric softener on moisture wicking fabric
Washing. Do not use fabric softeners, or dryer sheets. The best way to keep the wicking function in the sleepwear is to wash the garments without softener and then let it hang dry. They will dry quickly on a hanger. If you by accident use fabric softener then wash them again without softener a couple of times and you will wash out the softener.
Fabric softener is like wax, it is coating the material to make it feel smooth and soft, and by doing this the softener will also “coat in” the wicking function so it wont wick as good.
All in all - a better nights sleep, and a drier day.
