Do Under Armour Shirts Shrink? Unveiling the Truth Behind the Fabric

Yes, Under Armour shirts can shrink, but the extent of shrinkage depends heavily on the fabric composition, washing and drying methods, and the specific type of shirt. Generally, shirts made with a higher percentage of natural fibers like cotton are more prone to shrinking compared to those primarily composed of synthetic materials like polyester or elastane. Let’s delve deeper to understand the factors at play and how to minimize unwanted shrinkage.

Understanding Under Armour Fabrics and Shrinkage

Under Armour is renowned for its innovative fabrics designed for athletic performance. However, understanding the blend of materials is crucial for predicting how your shirt will respond to washing and drying. Here’s a breakdown:

The Role of Cotton

Cotton is a natural fiber prized for its comfort and breathability. However, cotton fibers tend to shrink when exposed to high heat. This is because the fibers swell when wet and then contract as they dry, particularly under high temperatures. Under Armour shirts that are a blend of cotton and synthetic fibers will likely experience some shrinkage, especially if not cared for properly.

The Power of Synthetics: Polyester and Elastane

Polyester and elastane (often sold as Spandex or Lycra) are synthetic fibers that offer excellent durability, moisture-wicking properties, and resistance to shrinking and stretching. Under Armour’s performance apparel often utilizes these materials to minimize shrinkage and maintain shape. Shirts made primarily of polyester or a polyester blend are generally less prone to shrinking than those containing a significant amount of cotton.

HeatGear vs. ColdGear: Material Matters

Under Armour’s HeatGear line is designed for warm weather and often incorporates a blend of synthetic fibers designed for breathability and moisture transport. ColdGear apparel, on the other hand, is intended for colder conditions and might contain a higher percentage of cotton or other insulating fibers. Therefore, ColdGear shirts might be more susceptible to shrinkage compared to HeatGear shirts. Always check the care label to understand the fabric composition and recommended washing instructions.

Minimizing Shrinkage: Best Practices for Washing and Drying

Proper care is essential to prolong the life of your Under Armour shirts and minimize shrinkage. Here are some guidelines:

Washing Instructions: The Key to Longevity

Read the Care Label: This is the single most important step. The care label provides specific instructions from the manufacturer regarding washing temperature, drying methods, and ironing.
Wash in Cold Water: Cold water is generally gentler on fabrics and helps prevent shrinkage, fading, and damage.
Use a Mild Detergent: Harsh detergents can break down fibers and contribute to shrinkage. Opt for a mild detergent specifically designed for activewear or delicate fabrics.
Wash Inside Out: Turning your shirts inside out protects the outer surface from friction and abrasion during washing, preserving the color and print.
Avoid Overloading the Washing Machine: Overloading can prevent proper cleaning and rinsing, potentially leading to detergent buildup and damage to the fabric.

Drying Techniques: A Delicate Balance

Air Drying is Best: Air drying is the safest method to prevent shrinkage. Hang your shirts on a clothesline or lay them flat on a drying rack.
Tumble Dry on Low Heat: If you must use a dryer, select the lowest heat setting possible. High heat is a major contributor to shrinkage.
Remove Shirts Promptly: Once the drying cycle is complete, remove your shirts immediately to prevent wrinkles and further shrinkage.
Consider a Garment Bag: Using a mesh garment bag can protect your Under Armour shirts from snagging or rubbing against other items in the dryer.

What to Do If Your Under Armour Shirt Has Already Shrunk

Even with the best care, some shrinkage may still occur. Here are a few potential remedies:

Stretching Techniques

Soak and Stretch: Soak the shirt in lukewarm water and gently stretch it back to its original size while it’s wet. Lay it flat to dry.
Wear While Damp: While slightly damp, wear the shirt and gently stretch it as you move around. This can help the fabric regain some of its original shape.
Use a Garment Steamer: Steaming can help relax the fibers and allow you to gently stretch the shirt.

Preventing Future Shrinkage

Pre-Shrink Cotton Blends: Before wearing a new cotton-blend Under Armour shirt, consider washing and drying it according to the care instructions to pre-shrink it. This will help minimize future shrinkage.
Buy a Size Up: If you are concerned about shrinkage, especially with cotton blends, consider buying a size larger than you normally wear.

Frequently Asked Questions (FAQs) About Under Armour Shirt Shrinkage

Here are some frequently asked questions about Under Armour shirt shrinkage to provide further clarification:

1. Do all Under Armour shirts shrink equally?

No. The amount of shrinkage varies based on the fabric composition. Shirts with a higher percentage of cotton will shrink more than those made primarily of synthetic fibers.

2. Does HeatGear shrink more than ColdGear?

Generally, no. HeatGear is typically made with more synthetic materials, making it less prone to shrinking than ColdGear, which may incorporate cotton or other natural fibers.

3. Can I shrink an Under Armour shirt intentionally?

While possible, it’s not recommended. Intentionally shrinking a shirt can damage the fabric and alter its performance properties.

4. Will washing my Under Armour shirt in hot water guarantee shrinkage?

Washing in hot water significantly increases the likelihood of shrinkage, especially for cotton-blend shirts. It’s best to stick to cold water.

5. Is it okay to iron my Under Armour shirt?

Check the care label. Some Under Armour shirts can be ironed on a low setting, while others should not be ironed at all.

6. Does dry cleaning affect the shrinkage of Under Armour shirts?

Dry cleaning is generally safe for most Under Armour shirts, but always check the care label to ensure the fabric is compatible with dry cleaning solvents.

7. How can I tell if my Under Armour shirt is pre-shrunk?

The care label may indicate if the shirt is pre-shrunk. If not, you can assume that a cotton-blend shirt may experience some initial shrinkage.

8. Will the color of my Under Armour shirt affect its shrinkage?

The color itself does not directly affect shrinkage. However, darker colors may fade more noticeably if washed in hot water, making shrinkage seem more apparent.

9. What type of detergent is best for preventing shrinkage?

Use a mild detergent specifically designed for activewear or delicate fabrics. Avoid harsh detergents that can damage fibers.

10. Can I use fabric softener on my Under Armour shirts?

Generally, avoid using fabric softener on Under Armour shirts, as it can coat the fibers and reduce their moisture-wicking properties.

11. How long will an Under Armour shirt last if I care for it properly?

With proper care, an Under Armour shirt can last for several years. However, the lifespan will depend on the frequency of wear and the intensity of activity.

12. Is it possible to unshrink an Under Armour shirt that has shrunk significantly?

While stretching techniques can help, it may not be possible to completely restore a shirt to its original size if it has shrunk significantly. Prevention is key.

By understanding the fabric composition of your Under Armour shirts and following proper washing and drying techniques, you can significantly minimize shrinkage and prolong the life of your favorite athletic apparel. Remember to always consult the care label for specific instructions and prioritize gentle care to maintain the performance and fit of your garments.
