Buying Guide for Under Armor Rash Guard

Understanding What a Rash Guard Is

When I first looked into rash guards, I realized they are more than just a simple piece of athletic wear. A rash guard is designed to protect your skin from irritation caused by abrasion, sun exposure, and sometimes even jellyfish stings during water activities. Under Armour rash guards, in particular, combine performance fabric with a snug fit to give you both comfort and protection.

Material and Fabric Technology

One of the first things I considered was the material. Under Armour typically uses polyester and elastane blends, which offer excellent stretch, durability, and moisture-wicking properties. This means the rash guard stays dry and light even during intense workouts or long hours in the sun. I also appreciated the quick-drying feature, which made transitions between water and land activities much more comfortable.

Fit and Size Considerations

Getting the right fit was crucial for me. Rash guards are meant to be snug to prevent water from getting trapped between the fabric and skin, which can cause chafing. However, it shouldn’t be so tight that it restricts movement or feels uncomfortable. Under Armour provides detailed sizing charts, and I found measuring my chest, waist, and arm length helped me pick a size that fit perfectly.

Sun Protection Factor (UPF Rating)

I always check the UPF rating when buying a rash guard because sun protection is a big priority. Many Under Armour rash guards come with built-in UPF 30+ or higher, shielding my skin from harmful UVA and UVB rays. This feature gave me peace of mind during long outdoor sessions without having to constantly reapply sunscreen on covered areas.

Style and Design Choices

While performance is key, I also like to feel good wearing my rash guard. Under Armour offers various styles, from long sleeves to short sleeves, and different color options. I chose based on the activity and weather conditions—long sleeves for cooler days or more sun protection, and short sleeves for warmer climates or layering under other gear.

Durability and Care Instructions

Because I use my rash guard frequently, I wanted to ensure it would last. Under Armour’s quality construction means the fabric resists pilling and fading. Following the care instructions—like washing in cold water and avoiding fabric softeners—helped maintain its elasticity and color over time.

Price and Value for Money

I weighed the price against the features and durability. While Under Armour rash guards can be a bit more expensive than generic brands, the performance benefits and lasting quality made it worth the investment for me. It’s important to consider how often you’ll use the rash guard and the kind of activities you do when evaluating value.

Final Thoughts

Buying an Under Armour rash guard was a great decision for my active lifestyle. By focusing on material, fit, sun protection, and durability, I found a product that not only met but exceeded my expectations. Whether you’re into surfing, running, or gym workouts, a good rash guard can make a noticeable difference in comfort and performance.
