Why Under Armour Rash Guard Is Necessary
From my experience, wearing an Under Armour rash guard has been a game-changer for my outdoor activities, especially when I’m surfing, swimming, or even hiking. The first thing I noticed is how it protects my skin from harsh sun exposure. The built-in UPF protection means I don’t have to constantly worry about sunburn, which makes my time outside much more enjoyable and safe.
Another reason I find it necessary is the way it prevents chafing and irritation. When I’m active, regular shirts can rub against my skin and cause discomfort, but the snug, smooth fabric of the Under Armour rash guard stays in place and reduces friction. Plus, it dries quickly, which keeps me comfortable even after I get out of the water.
Lastly, I appreciate how durable and lightweight it is. It feels like a second skin but still offers excellent support and compression. Whether I’m training hard or just out for a casual adventure, my Under Armour rash guard helps me perform better while protecting my body. For me, it’s an essential piece of gear that I wouldn’t leave home without.
My Buying Guides on Under Armour Rash Guard
When I decided to invest in an Under Armour rash guard, I wanted something that would offer both protection and comfort. Over time, I’ve learned what features really matter and how to choose the best one for my needs. Here’s my detailed guide to help you pick the right Under Armour rash guard.
Understanding What a Rash Guard Is
First off, a rash guard is a close-fitting shirt designed to protect your skin from rashes caused by abrasion, sunburn, or irritation from surfboards and other equipment. Under Armour’s rash guards combine this protection with their signature moisture-wicking and compression technology, which I found crucial during intense workouts or water sports.
Material and Fabric Technology
One of the first things I check is the fabric. Under Armour typically uses a blend of polyester and elastane, which gives their rash guards a great stretch and durability. The UA Tech fabric is lightweight and dries quickly—perfect if you’re in and out of the water like me. Also, many models include UPF 50+ sun protection, which is a must-have if you’re spending hours outdoors.
Fit and Size Considerations
Under Armour rash guards are designed to be snug, providing compression benefits and reducing drag in the water. When I bought mine, I made sure to check the size chart carefully because a proper fit enhances mobility and comfort. If you prefer a bit more room, consider sizing up, but remember that too loose a fit can reduce the effectiveness of the rash guard.
Design and Style Options
I appreciate that Under Armour offers a variety of colors and patterns—from classic black to vibrant prints. Choosing a design that you feel confident wearing can boost your motivation to stay active. Some models also have different sleeve lengths (short, long, or ¾ sleeves), so pick one that suits your activity and weather conditions.
Purpose and Activity Type
Think about how you’ll use your rash guard. For surfing or paddleboarding, I prefer long sleeves for maximum sun protection. For gym workouts or running, a short sleeve might be more comfortable. Under Armour has options tailored for different activities, so identifying your primary use helps narrow down the best choice.
Durability and Care Instructions
Since rash guards get a lot of wear and exposure to sun, salt, or chlorine, durability is important. Under Armour gear generally holds up well, but I always follow the care instructions—cold wash and air dry—to maintain fabric quality and elasticity over time.
Price and Value
Under Armour rash guards are an investment, but in my experience, the quality justifies the price. Look out for seasonal sales or bundles if you want to save money. Sometimes, paying a little more upfront means better performance and longer-lasting gear.
Final Thoughts
Choosing an Under Armour rash guard comes down to your specific needs—activity type, fit preference, and design taste. By focusing on fabric technology, fit, and protection features, I found a rash guard that keeps me comfortable and protected during all my adventures. I hope this guide helps you find the perfect one for yourself!
