My Buying Guide on Under Armor Rash Guard

When I decided to invest in an Under Armor rash guard, I wanted to ensure I made an informed choice. Rash guards are not only essential for protecting my skin during water sports and workouts, but they also provide comfort and style. Here’s my comprehensive buying guide to help you choose the right Under Armor rash guard for your needs.

Understanding Rash Guards

Before diving into my recommendations, let’s talk about what a rash guard is. I found that these garments are designed primarily for water sports like surfing, swimming, and paddling. They offer protection against UV rays, abrasions from surfboards, and even jellyfish stings. For me, they also double as a great base layer for other activities, like running or weightlifting.

Key Features to Consider

Fabric and Comfort

When I chose my rash guard, I looked for a blend of materials that offered breathability and stretch. Under Armor typically uses a combination of polyester and elastane, which helps with moisture-wicking and allows for a full range of motion. I recommend checking the fabric’s weight too; lighter options are great for hot weather, while heavier fabrics can provide additional warmth.

Fit and Style

Fit is crucial for comfort. I prefer a snug fit that doesn’t feel restrictive. Under Armor offers different fits—fitted, loose, and compression. I found that the fitted option works best for my activities as it stays in place and reduces drag in the water. Style-wise, Under Armor has a variety of colors and designs, so I made sure to choose one that matched my personal taste.

UV Protection

One of the standout features of Under Armor rash guards is their UV protection. I always check the UPF rating before purchasing. A rash guard with a UPF of 30 or higher gives me peace of mind when I’m out in the sun for extended periods.

Durability

I’ve learned the hard way that durability is key, especially if I’m using my rash guard frequently. Under Armor is known for its quality, but I still look for reinforced seams and quality stitching. This ensures my rash guard can withstand the rigors of my activities, whether it’s the ocean waves or the gym floor.

Sizing Guide

Under Armor typically provides a sizing chart that I found useful when selecting my rash guard. I recommend measuring my chest, waist, and hips before making a purchase. I usually go for a size that allows me a bit of room for movement while still fitting snugly.

Price Range

I noticed that Under Armor rash guards come in a variety of price ranges. I set a budget before shopping, but I also consider the quality and features. Sometimes, spending a bit more upfront for a high-quality rash guard saves money in the long run since I won’t have to replace it as often.

Where to Buy

I’ve found that I can purchase Under Armor rash guards both online and in stores. Websites like Amazon, the official Under Armor site, and sporting goods stores often have great selections. I also keep an eye out for sales or discounts, especially during seasonal changes.

In my experience, investing in a good Under Armor rash guard has greatly enhanced my performance and comfort during both water sports and workouts. By considering the fabric, fit, UV protection, durability, sizing, and price, I was able to find the perfect rash guard for my needs. I hope this guide helps you make an informed decision as well!
