What is Under Armour Made Of? Unveiling the Secrets Behind Performance Apparel

Under Armour’s success hinges on its innovative use of synthetic materials engineered to enhance athletic performance. While specific blends vary across different product lines, the core materials revolve around polyester, elastane (Spandex/Lycra), nylon, and, less frequently these days, cotton. These materials are often combined with proprietary technologies like HeatGear, ColdGear, and Storm to deliver specific benefits like moisture-wicking, temperature regulation, and water resistance. It’s not just about the fiber; it’s about the clever combination and engineering that defines the Under Armour edge.

The Core Components of Under Armour Apparel

Under Armour’s commitment to performance is reflected in its meticulous material selection. Let’s break down the primary materials and their respective roles in shaping the brand’s distinctive identity:

Polyester: The Workhorse of Performance

Polyester is the undisputed champion in Under Armour’s fabric arsenal. Renowned for its durability, resistance to shrinking and stretching, and exceptional moisture-wicking properties, polyester forms the base for many of their garments. It efficiently pulls sweat away from the skin, keeping athletes cool and dry during intense workouts. Furthermore, polyester’s ability to hold vibrant colors and resist fading makes it ideal for activewear that maintains its aesthetic appeal over time. Beyond pure polyester, you’ll often find it in blends to enhance specific performance characteristics.

Elastane (Spandex/Lycra): The Secret to Flexibility

Elastane, known by brand names like Spandex and Lycra, is the key ingredient for providing stretch and freedom of movement. It’s typically used in small percentages (between 5-20%) blended with other fibers like polyester or nylon. This addition allows Under Armour apparel to conform snugly to the body without restricting mobility. The superb elasticity enables a full range of motion, crucial for optimal athletic performance in any sport.

Nylon: Strength and Smoothness Combined

Nylon offers a unique blend of strength, abrasion resistance, and a smooth, comfortable feel. While not as prevalent as polyester, nylon is strategically used in Under Armour garments, particularly in areas requiring extra durability, such as waistbands, compression wear, and outer layers. Nylon’s smooth texture also contributes to a more comfortable next-to-skin feel. It also excels at quick-drying properties and maintains its shape well after repeated use.

The Role of Cotton (Less Common Today)

While Under Armour initially focused primarily on synthetic materials, cotton has occasionally been incorporated into some product lines, usually in blends. Cotton’s comfort and breathability are appealing, however, it holds moisture, which can be detrimental to performance. Therefore, you’ll find cotton far less frequently in Under Armour’s performance-oriented apparel and more often in casual wear where performance isn’t the primary concern.

Under Armour’s Proprietary Fabric Technologies

Beyond the base materials, Under Armour’s innovative technologies give their products a significant edge.

HeatGear: Staying Cool Under Pressure

HeatGear is engineered to keep athletes cool, dry, and light during hot weather or intense workouts. It achieves this through its superior moisture-wicking properties and breathability. The fabric actively transports sweat away from the skin, allowing it to evaporate quickly and preventing overheating. This is a cornerstone technology for many of Under Armour’s training and performance apparel.

ColdGear: Conquering the Cold

ColdGear technology is designed to keep athletes warm, dry, and comfortable in cold weather. Unlike HeatGear, ColdGear utilizes a dual-layer fabric that traps heat close to the body while wicking away moisture. This combination provides insulation without the bulk, allowing for unrestricted movement during outdoor activities in colder conditions. Many ColdGear garments feature a brushed interior for added warmth and comfort.

Storm Technology: Weathering the Elements

Storm technology provides a water-resistant finish that repels rain and snow without sacrificing breathability. This technology is applied to various Under Armour apparel items, including jackets, pants, and hats, to offer protection from the elements. The DWR (durable water repellent) finish ensures that water beads up and rolls off the fabric, keeping athletes dry and comfortable even in wet conditions.

Understanding the Fabric Blends

Under Armour rarely relies on single-fiber fabrics. Instead, they strategically blend different materials to optimize performance characteristics. Here are some common blends you might encounter:

• Polyester/Elastane: This blend provides a balance of durability, moisture-wicking, and stretch. It’s commonly found in base layers, training apparel, and compression wear.
• Nylon/Elastane: This blend offers superior strength, abrasion resistance, and stretch. It’s often used in leggings, tights, and swimwear.
• Polyester/Cotton: While less common in high-performance gear, this blend provides a balance of comfort, breathability, and affordability. It’s often found in casual wear and t-shirts.
• Tri-Blends (Polyester/Cotton/Rayon): This blend enhances softness and drape for a more relaxed fit. Often found in t-shirts and hoodies.

The Importance of Fabric Construction and Finishing

The material composition is only part of the story. Fabric construction (how the fibers are woven or knitted together) and finishing (treatments applied to the fabric) play a crucial role in determining the final performance of the garment. For example, a warp-knit fabric is more durable and resistant to snagging than a weft-knit fabric. Similarly, a moisture-wicking finish can enhance the performance of even a basic polyester fabric.
