"When we learned from our customers that they were having tremendous issues with high-stretch fabrics, we said, 'How can we make this better?' We worked with our customers to prove our hypothesis that adding LYCRA® T400® fiber into the yarn could really make a difference. The resulting product has truly revolutionized denim.”
