The KÜHL Khloe SS™ features Wildfibre™ organic cotton and Tencel for softness and performance. Luxurious slub jersey body fabric with cotton woven mechanical stretch. Mechanical stretch does not come from elastic fabric but from the knitting process. Added length in the loom is then shrunk for fit but retains room to stretch. The result with mechanical stretch is fit and function that is more resilient than stretch fabrics. On the back, notice the gathering at the back yoke. With short sleeves for warm weather and freedom of movement.
