Under Armour Leggings vs. Lululemon Leggings Comparison

Price & Value

There's a clear price difference between the two brands. Under Armour leggings are more accessible, retailing between $40 and $80. This makes them a strong choice for those who need functional, reliable workout gear without a major investment. The value lies in their proven performance and durability for demanding training.

Lululemon leggings are a premium purchase, priced from $80 to $150. The higher cost is justified by their proprietary, luxurious fabrics, meticulous construction, and superior fit that combines comfort and style. Many owners consider them a worthy investment due to their longevity and versatility as both activewear and everyday apparel.

Quality & Materials

Both brands produce high-quality leggings, but their materials serve different purposes. Under Armour uses technical fabrics like HeatGear that feel slick and compressive, and are engineered to pull sweat away from the body. They feel like true athletic gear - effective, supportive, and ready for work.

Lululemon's focus is on fabric feel and performance. Their signature materials like Nulu™ (used in Align leggings) are famously buttery-soft and weightless, offering moderate compression and unmatched comfort. Other fabrics like Everlux are designed for high-sweat sessions while maintaining a softer touch than competitors. The overall feel is more luxurious and R&D is focused on creating a "hugged" sensation.

Fit & Sizing

Under Armour leggings offer a standard fit, generally true to size with an XS-XXL range. The fit is secure and athletic, especially in compression models, but without the precision tailoring of more premium brands. They get the job done for workouts but may not offer the same body-contouring effect.

Lululemon is known for its precise and flattering fit. Using a 0-14+ numerical sizing system, their leggings are designed to contour and flatter curves while staying perfectly in place. The high-waisted designs are particularly popular for their comfort, coverage, and gentle shaping, contributing to their beloved "second-skin" reputation.

Style & Aesthetic

Under Armour's aesthetic is distinctly athletic and functional. Designs are often sporty, with visible logos, angular seams, and a focus on performance. While they offer various colors, the overall look is geared toward the gym, track, or field.

Lululemon offers a more minimalist, fashion-forward aesthetic that easily transitions from a spin class to brunch. With minimal branding, a variety of on-trend colors, and incredibly flattering silhouettes, their leggings are often worn as a fashion staple, making them far more versatile for everyday life.

Which One Should You Choose?

Both brands offer excellent leggings, but they are designed for very different consumers and priorities.

Choose Under Armour Leggings if:

• You prioritize performance for high-intensity, high-sweat workouts.
• You want effective compression and muscle support during training.
• Your budget for a pair of leggings is under $80.
• You prefer a classic athletic look and aren't concerned with fashion versatility.

Choose Lululemon Leggings if:

• You value a luxurious, buttery-soft fabric feel and "barely there" comfort.
• You want leggings that are versatile enough for workouts, errands, travel, and lounging.
• A flattering, body-contouring fit is a top priority for you.
• You are willing to invest in premium quality that is known to last for years with proper care.

Lululemon focuses on a premium lifestyle experience, using proprietary, ultra-soft fabrics that deliver unmatched comfort and a flattering fit for both workouts and everyday wear.

Are Lululemon leggings worth the money?

For many, yes. Their high price reflects luxurious proprietary fabrics, exceptional comfort, a flattering fit, and great durability when cared for properly. Their versatility for both fitness and daily fashion adds to their value, as one pair can serve multiple purposes.

Are Under Armour leggings good for running?

Yes, Under Armour leggings are excellent for running. Their HeatGear fabric is designed to be lightweight and wick sweat effectively, while their compression fits can help with muscle support and reduce fatigue during long runs.

Which brand is more durable?

Both brands are durable, but in different ways. Under Armour leggings are built to withstand abrasion and intense physical stress. Lululemon leggings are known for their longevity and excellent shape retention over hundreds of washes, provided you follow care instructions (wash cold, tumble dry low) to protect the specialty fabrics.

How do the sizes compare? (Under Armour vs. Lululemon Sizing)

Under Armour uses a standard alpha sizing system (XS, S, M, L). Lululemon uses a numerical system (0, 2, 4, 6) which offers a more precise fit. Most people find both brands to be true to size, but if you're between sizes, you may have better luck with Lululemon's more granular options.

Are Lululemon leggings see-through?

Lululemon leggings are well-known for their opacity and passing the "squat test." Most of their fabrics, like Luon and Everlux, are designed to remain opaque even when stretched. As with any brand, choosing the correct size is crucial to ensure full coverage.

Which brand is better for high-intensity workouts?

Under Armour often has the edge for high-intensity workouts like HIIT, CrossFit, or heavy weightlifting due to its focus on durable, compressive, and highly moisture-wicking fabrics that are built to handle extreme physical demands.

How should I care for my leggings to make them last?

For both brands, it's best to wash them in cold water with like fabrics and avoid fabric softeners, which can degrade performance fabrics. To protect Lululemon's softer materials from pilling, avoid washing them with abrasive items like towels or denim. Tumble drying on low heat or hanging to dry is recommended for both.
