Nulu Fabric Composition

Nulu fabric is one of the proprietary fabrics developed by Lululemon. It’s known for being incredibly soft, lightweight, and breathable. The fabric is designed to offer a “barely-there” feel, making it ideal for yoga and other activities where comfort and freedom of movement are essential. Lululemon often uses Nulu fabric in leggings, sports bras, and other activewear items.

Nulu is made primarily from elastane (a.k.a. “Spandex” and “Lycra”) and nylon and is specifically engineered to be moisture-wicking and four-way stretchable. This blend of features makes it a popular choice for those who engage in low-impact sports or activities that require a high degree of flexibility.

However, the soft texture may make it less durable than other fabrics, so handling Nulu garments carefully is usually advised to prolong their life. View our care recommendations for yoga pants »

Elastane / Spandex / Lycra

Elastane is a synthetic fiber known for its exceptional elasticity. It’s also called “spandex” in the United States and other countries. The term “spandex” is actually an anagram of the word “expands.” Elastane is often used in garments where stretch is desired, including leggings, swimwear, sportswear, and even more formal clothing like suits to provide a bit of give.

Lycra is a brand name for a type of elastane fiber developed by DuPont in 1958. Over time, the name “Lycra” has become synonymous with elastane. However, it’s important to note that Lycra is a specific trademarked brand.

Spandex is the generic name for the synthetic fiber known for its exceptional elasticity, while Lycra is a brand name for spandex created by the chemical company DuPont. In other words, all Lycra is spandex, but not all spandex is Lycra.

Here are some key features of elastane:

  • Highly Elastic: Elastane can stretch up to five times its original length and return to its original shape, providing garments with excellent flexibility and comfort.
    Strong and Durable: Despite its elasticity, elastane is strong and durable. However, it’s usually blended with other fibers like cotton, polyester, or nylon to enhance its durability further.
  • Moisture-Wicking: Elastane is not particularly good at absorbing moisture but is often blended with other fibers, thus giving the garment good moisture-wicking properties.
  • Lightweight: The fiber is light, and garments that include elastane are also generally lightweight.
  • Smooth and Soft: Elastane is often used in “second-skin” garments because it can create a very smooth and fitted look without feeling too constrictive.
  • Sensitive to Heat: Elastane is sensitive to high temperatures and can lose its elasticity if exposed to hot water or a hot dryer, so care instructions usually recommend cold washing and air drying.
  • Chemical Resistance: It has a reasonable degree of resistance to body oils, lotions, and sweat, making it popular for swimwear and sportswear.
  • Blending: While it’s uncommon to find garments made entirely of elastane, it’s often blended in small percentages with other fibers to provide stretch. For example, a pair of jeans might be 98% cotton and 2% elastane.


Nylon is a synthetic polymer initially developed as a replacement for silk, and it has since become one of the most widely used synthetic fibers. DuPont first introduced it in 1938 and quickly gained popularity due to its strength, elasticity, and resistance to abrasion.

Here are some key features of nylon:

  • Durability: One of the most significant benefits of nylon is its durability. It is strong, resistant to abrasion, and generally long-lasting. This makes it suitable for use in a wide range of garments, including outerwear, swimwear, and sportswear.
  • Elasticity: Nylon has good stretch and recovery properties, which makes it a popular choice for garments that need to move with the body, like leggings or athletic apparel.
  • Moisture-Wicking: Unlike natural fibers like cotton, nylon doesn’t absorb much moisture, which makes it good at wicking moisture away from the body. This is particularly useful in sportswear.
  • Lightweight: Nylon fabric is generally lightweight and has a smooth texture. Garments made from nylon are often lightweight, making them comfortable to wear.
  • Quick-Drying: One of the advantages of nylon is that it dries quickly, which makes it popular for outdoor and athletic wear.
  • Chemical Resistance: Nylon is resistant to oils, chemicals, and other substances, which can make it more durable and versatile than other types of fabric.
  • UV Resistance: Some nylon fabrics are treated to be resistant to UV radiation, making them a good choice for outdoor wear.
  • Heat Sensitivity: Like many synthetic fibers, nylon can be sensitive to high temperatures and may melt or become deformed when exposed to heat. Always follow care instructions when laundering nylon garments.
  • Cost: Nylon is generally less expensive than many natural fibers, making it a cost-effective choice for many garments.
  • Environmental Impact: On the downside, nylon is a petroleum-based product, and its production is energy-intensive, which raises environmental concerns.

Nylon is often blended with natural and synthetic fibers to combine the best features of each. For example, adding a bit of elastane or Lycra can enhance the fabric’s stretchability while blending it with cotton can improve comfort.

Due to its versatility, nylon is used in a wide variety of applications beyond clothing, including ropes, parachutes, fishing nets, and more.

  1. postergirlcoollikeme

    I tried these shorts on in the store, and they are sooooo cute! I absolutely fell in love with them. The waistband and the seam placement are incredibly flattering. They really accentuate all the right curves. I couldn’t resist getting them. They’re definitely a must-have!

    I went a size up from my usual align legging size and grabbed a size 6 in these shorts. The nulu part underneath the mesh top layer is like a mini biker short, though it’s pretty short on its own. But honestly, I’m cool with it because the mesh layer goes longer and covers my booty, which is a plus!

    The back and top of the shorts could definitely be tighter, though. But if I went down a size, I don’t think they’d fit over my butt and hips.

    But overall, these shorts are just super comfy and cute! I can totally see myself wearing them casually!

    I have the Aerie version of these shorts and I’m absolutely obsessed with them! They are seriously amazing.
