The Fabric Technology Behind Under Armour Shirts

Under Armour shirts are known for their high-performance qualities and exceptional comfort. The brand has pioneered innovative fabric technologies to enhance athletic performance. Understanding what Under Armour shirts are made of can give us insight into their superior quality and functionality.

1. HeatGear Fabric

Under Armour utilizes a variety of fabrics in their shirt construction, and one of their most renowned materials is HeatGear fabric. HeatGear is designed to wick sweat away from the skin, keeping athletes cool, dry, and comfortable during intense workouts or hot weather conditions. The fabric is ultra-lightweight, allowing for maximum breathability. It also features a four-way stretch, ensuring flexibility and freedom of movement.

HeatGear fabric is made of a blend of synthetic materials, including polyester, elastane, and nylon. Polyester provides durability and quick-drying properties, while elastane gives the fabric its stretchability. Nylon adds strength and abrasion resistance to the fabric, ensuring it can withstand rigorous training sessions.

This combination of materials in HeatGear fabric makes it ideal for activities that generate a lot of sweat, such as running, basketball, or high-intensity interval training (HIIT). It offers a compression-like fit without restricting movement, making it a favorite among athletes who value performance and comfort.

Benefits of HeatGear Fabric:

  • Moisture-wicking to keep the skin dry
  • Lightweight and breathable
  • Four-way stretch for flexibility
  • Durable and resistant to abrasion

2. ColdGear Fabric

In contrast to HeatGear, Under Armour also offers shirts made with their ColdGear fabric, which is specifically designed to keep athletes warm in cold weather conditions. ColdGear fabric features a dual-layer construction that traps heat close to the body while wicking moisture away.

ColdGear fabric is composed of a blend of materials, typically polyester and elastane, similar to HeatGear. The inner layer of the fabric is soft and brushed, providing a comfortable feel against the skin, while the outer layer offers protection against the elements.

These shirts are designed to be worn as a base layer, providing insulation without adding bulk. They are often used for outdoor activities like hiking, skiing, or winter sports. The moisture-wicking properties of ColdGear fabric ensure that sweat is quickly moved away from the body, preventing discomfort and chilling.

Benefits of ColdGear Fabric:

  • Provides warmth and insulation in cold weather
  • Inner layer feels soft and comfortable
  • Moisture-wicking to keep the body dry
  • Designed to be worn as a base layer

3. Threadborne Fabric

Under Armour's Threadborne fabric is yet another innovation that has revolutionized their shirt construction. Threadborne utilizes a unique microthread technology that enhances the fabric's performance and comfort.

Microthreads are small fibers that are woven into the fabric, resulting in a softer feel, superior stretch, and excellent breathability. The technology allows for better moisture management, keeping athletes dry and comfortable even during intense workouts. Threadborne fabric also offers a lightweight and quick-drying performance.

The composition of Threadborne fabric varies, but it often includes a blend of polyester and elastane. This combination ensures durability, flexibility, and excellent moisture-wicking capabilities.

Benefits of Threadborne Fabric:

  • Soft and comfortable on the skin
  • Superior stretch and breathability
  • Moisture-wicking and quick-drying
  • Durable and flexible

4. Charged Cotton Fabric

While synthetic fabrics dominate Under Armour's collection, they also offer shirts made with Charged Cotton fabric, which combines the benefits of cotton with enhanced performance features.

Charged Cotton fabric is made of a blend of cotton, polyester, and elastane. The cotton component provides the comfort and natural feel of traditional cotton, while polyester improves durability and moisture-wicking capabilities. Elastane is included for flexibility and stretch.

Charged Cotton shirts are great for athletes who prefer the softness and breathability of cotton but still require performance-enhancing features. The fabric dries faster than regular cotton, making it suitable for workouts and casual sports activities.

Benefits of Charged Cotton Fabric:

  • Combines the comfort of cotton with performance features
  • Dries faster than regular cotton
  • Moisture-wicking capabilities
  • Offers flexibility and stretch
