This product was developed using the highest quality long staple cotton available in the market. It provides the highest physical strengths and the longest lifetime in any of our fabrics, and has been used for decades in lined and unlined offshore garments, as well as for refinery garments. This product is THE original offshore fabric in the market place, which often others have tried to copy but which still never has been beaten in performance. Quality concerned end users are still asking for the original RigChief fabric when specifying garment needs.
