  • Information :
    A new generation performance cotton by Cordura® and Cotton Incorporated. The technologies combine the tried and true, long-lasting durability of CORDURA® NYCO technique and the comfort of cotton. STORM COTTON™ is a finish applied to cotton fiber that effectively repels liquids and still allows for moisture vapor to pass through the fabric so it can move away from the body and dissipate into the environment naturally – helping keep the wearer more cool and comfortable. Because this special finish minimizes the amount of water that a cotton fabric can absorb, garments made with STORM COTTON™ technology are engineered to dry much faster than those made with untreated cotton which helps to minimize the amount of time and energy required for laundering.
