My Buying Guide on Under Armor Rash Guard

When I first started looking for a rash guard, I wanted something that would provide comfort, protection, and style while engaging in water sports and workouts. After some research and personal experience, I’ve put together this guide to help you navigate through the options and find the perfect Under Armor rash guard for your needs.

Why Choose Under Armor?

Under Armor has established a solid reputation in the athletic wear industry, and for good reason. Their rash guards are designed with performance in mind. I appreciate that they use high-quality materials that offer durability and flexibility, making them ideal for intense activities like surfing, swimming, or grappling.

Types of Under Armor Rash Guards

  1. Long Sleeve vs. Short Sleeve:
  • Long Sleeve: I prefer long sleeves for additional sun protection and warmth in cooler waters. They also offer better coverage against abrasions.
  • Short Sleeve: If you’re looking for something cooler for hot days, short sleeves are great. They allow for better airflow while still protecting against rashes.
  1. Fitted vs. Loose Fit:
  • Fitted: I find that fitted rash guards provide better support and reduce drag in the water, which is essential for activities like swimming.
  • Loose Fit: If you prefer a more relaxed feel, a loose fit might be the way to go. This style can provide more comfort for casual wear or lounging.

Fabric and Technology

Under Armor uses a variety of fabrics that enhance performance. Here are a few things I look for:

  • Moisture-Wicking: I love that their fabric pulls sweat away from my body, keeping me dry and comfortable during workouts.
  • UV Protection: For outdoor activities, I always check for UPF ratings. A good rash guard should protect my skin from harmful UV rays.
  • Anti-Odor Technology: I appreciate the anti-odor properties that help keep my rash guard fresh even after multiple uses.

Size and Fit

Finding the right size is crucial. I recommend checking the size chart on the Under Armor website, as sizing can vary. I usually opt for a snug fit to ensure that the rash guard stays in place during my activities. Remember, it should be tight but not restrictive.

Price Range

Under Armor rash guards typically range from $30 to $70, depending on the style and technology features. I’ve found that investing in a quality rash guard pays off in the long run, as durability and performance are often worth the extra cost.

Care Instructions

To prolong the life of my rash guard, I always follow proper care instructions. Here are some tips I stick to:

  • Rinse immediately after use to remove saltwater or chlorine.
  • Wash in cold water and avoid using fabric softeners.
  • Hang to dry instead of using a dryer to maintain elasticity.

Where to Buy

You can find Under Armor rash guards at various retailers, including their official website, sporting goods stores, and online marketplaces like Amazon. I recommend checking for sales or discounts to get the best deal.

Final Thoughts

Choosing the right Under Armor rash guard has made a significant difference in my comfort and performance during water sports and workouts. By considering the type, fit, fabric, and price, you can find a rash guard that suits your needs perfectly. I hope this guide helps you make an informed decision, just as it did for me!
