Nulux is made from which of the following fibers?

Nulux is a technical fabric developed by Lululemon that is designed to be lightweight, breathable, and moisture-wicking, making it ideal for athletic wear. The correct composition of Nulux includes Nylon and Lycra, which provide durability and stretch. Nylon is known for its strength and resistance to wear, while Lycra (often recognized by its various brand names like Spandex) offers superior elasticity, allowing garments made from Nulux to maintain their shape and provide support during physical activities. This combination not only enhances performance but also contributes to the comfort and fit that athletes seek in their apparel.

The other combinations listed do not align with the properties and intended use of Nulux. Silk and cashmere tend to be more luxurious materials, not typically used for performance fabrics. Wool and nylon may provide some breathability but would not offer the lightweight characteristics that define Nulux. Lastly, acrylic and polyester are generally more suited for warmth and insulation, lacking the technical benefits that active fabrics like Nulux are known for.
