Why Under Armour Rash Guard Is Necessary
From my experience, an Under Armour rash guard is a game-changer for anyone who spends time in the water or engages in outdoor sports. First, it offers excellent protection against rashes caused by friction, whether from a surfboard, wetsuit, or just constant movement. I’ve noticed that wearing one significantly reduces skin irritation, making my sessions much more comfortable.
Another reason I rely on my Under Armour rash guard is its ability to provide UV protection. When I’m out under the sun for hours, it shields my skin from harmful rays, which is something regular shirts just can’t do as effectively. Plus, the material wicks away sweat and dries quickly, keeping me cool and comfortable even during intense workouts or long days at the beach.
Lastly, the fit and durability of the Under Armour rash guard make it a staple in my gear. It hugs my body without restricting movement, and I’ve found it holds up well through frequent use and washing. For me, it’s not just about protection—it’s about enhancing my performance and comfort every time I’m active outdoors.
My Buying Guides on Under Armor Rash Guard
When I first started looking for an Under Armor rash guard, I realized there were several important factors to consider to get the best fit and performance. Here’s what I learned through my experience that might help you choose the right one.
1. Understand What a Rash Guard Is
Before diving into specific Under Armor options, I made sure I knew exactly what a rash guard does. It’s a tight-fitting shirt designed to protect your skin from rashes caused by abrasion, sunburn, and sometimes even jellyfish stings. Under Armor rash guards also provide excellent moisture-wicking and quick-drying features, which is great for any water or workout activity.
2. Choose the Right Material
Under Armor rash guards are typically made from a blend of polyester and elastane (spandex). I found that this combo offers stretch, durability, and breathability. The elasticity ensures the rash guard moves with your body without restricting you, while the polyester helps wick sweat away. If you want extra comfort, look for versions with softer inner linings.
3. Pay Attention to Fit and Size
I learned that sizing is crucial because rash guards are meant to be snug but not uncomfortable. Under Armor usually offers a size chart—don’t just guess your size. I measured my chest, waist, and torso length, then compared those numbers to their chart. If you’re between sizes, I recommend sizing up slightly for better comfort, especially if you plan to wear it for long periods.
4. UV Protection Factor
One of the biggest reasons I bought an Under Armor rash guard was for sun protection. Most of their rash guards come with built-in UPF 50+ protection, which blocks out 98% of harmful UV rays. If you spend a lot of time outdoors, especially in water sports, this feature is a must-have.
5. Design and Style Preferences
Under Armor offers a variety of colors and designs. I picked a style that I liked visually but also one that had reflective elements for safety during early morning or late evening workouts. You can choose between long sleeve or short sleeve depending on your needs—long sleeves provide more coverage, while short sleeves are cooler in hot weather.
6. Durability and Care Instructions
I wanted a rash guard that would last through many washes and workouts. Under Armor products are known for their durability, but to keep my rash guard in good condition, I always followed the care instructions: wash in cold water, avoid fabric softeners, and air dry. This helped maintain the fabric’s elasticity and color.
7. Price and Value
Under Armor rash guards tend to be a bit pricier than generic brands, but I felt the investment was worth it for the quality, comfort, and protection. I looked for sales or deals to get a better price, and sometimes buying last season’s color can save money without sacrificing performance.
8. Read Reviews and Try It On
Finally, I always check user reviews to see how others felt about fit and durability. If possible, try the rash guard on before buying. Everyone’s body is different, so what fits me perfectly might feel tight or loose for you.
—
In summary, buying an Under Armor rash guard is about balancing fit, comfort, protection, and style. By focusing on these key areas, I found a rash guard that meets my needs and enhances my performance. Hopefully, my experience helps you find the perfect one too!
