The Nike golf apparel line delivers stylish looks that are performance-driven so that you can look, feel, and play your best.
Nike has been making golf apparel for decades, and they've been focused on general athletic apparel for even longer than that. You could say they know a thing or two about making performance athletic-wear. Much of the Nike Golf clothing line uses their proprietary Dri-Fit fabrics, first developed in 1991. Nike golf shirts and Nike golf pants almost exclusively use Dri-Fit materials.
Nike's Dri-Fit fabric is polyester-based and features a hydrophobic (water-repelling) action on the inside of the garment which quickly forces water to the outside of the garment, which is hydrophilic (water-attracting). This movement of moisture from the skin to the outside of the apparel quickly wicks moisture away from the skin, which increases evaporative cooling and makes you feel cooler. Once the moisture is drawn off your skin and moved to the outer layer of the garment, body heat and environmental factors help it to evaporate quickly.
What all of this means is that even if you are drenched in sweat, you will feel cooler than you would with a cotton fabric, and it will dry much faster than with cotton.
