X4zol™-J Fiber Technology for Performance Apparel

X4zol™-J Fiber Technology

A Revolution in Comfort

What if the next generation of apparel offered a better fit, with comfortable stretch and support, as well as cooling, breathability, and a sense of weightlessness on the body? It may be time for a revolution in comfort, driven by an innovative new fiber: X4zol™-J.

X4zol™-J Fiber

X4zol™-J, a thermoplastic polyurethane (TPU), is a revolutionary elastomeric monofilament that is manufactured differently from spandex, resulting in unique qualities that provide comfort above and beyond traditional stretch fibers. X4zol™-J is produced through a process of melt extrusion, which does not require the use of solvents. The melt extrusion process is cleaner, resulting in a finer and stronger monofilament than traditional spandex, exhibiting a superior stretch.

Spandex vs. X4zol™-J Fiber

Most spandex fibers exhibit a steeper stress/strain curve, illustrating low initial resistance to stretch, or elongation, and then a rapid increase in resistance to the point of full elongation, or breakage.

Benefits of X4zol™-J in Fabrics

  • Thinner and lighter, yet stronger and more durable
  • Comfortable stretch 
  • Breathable and cooling touch
  • Balanced 360° compression for enhanced fit
  • Sustainable benefits include processing at lower temperatures and recyclable* fiber
  • Engineered moisture movement throughout fabric


  • Athleisure/Yoga Wear
  • Intimates
  • Narrow Elastics
  • Denim
  • Stretch Fleece
  • Baselayer
  • Swimwear
  • Hosiery
  • Socks
  • Military
  • Footwear Uppers

*Recyclability is based on access to a readily available standard recycling program that supports such materials. Products may not be available in all areas.
