Buyer's Guide

Under Armour's long sleeve offerings blend moisture-wicking performance with temperature regulation, making them suitable for various activities and climates. Understanding key features and considerations will help you select the right long sleeve top for your needs.

Core Temperature Regulation

These shirts employ UA's moisture-management fabric technology to draw sweat away from the skin, keeping you dry and comfortable during workouts. Look for tighter weave densities for better wind protection in cooler conditions.

Moisture-Wicking and Drying Time

The primary function of long sleeve tops is to move perspiration away from your body. Opt for faster-drying materials with tighter yarn constructions, as thicker fabrics take longer to dry and may feel heavier when damp.

Fit and Tailoring

Under Armour offers various fit profiles depending on the specific style. For general fitness use, the Standard fit strikes a balance between form-fitting performance and everyday comfort. If you prefer a more relaxed silhouette, consider size options based on your usual shirt fit.

Additional Features to Consider

Many long sleeve options include seam-free construction to reduce irritation, while others incorporate stretchy materials for enhanced mobility. Look for reinforced stitching at stress points and tag-free designs to prevent chafing during workouts.

FAQ

What makes Under Armour long-sleeve shirts different from regular long-sleeves?

Under Armour's long-sleeve shirts combine everyday basics with moisture-wicking, temperature-regulating technology. These shirts pull sweat away from your skin to keep you dry, making them ideal for both casual wear and athletic activities.

The fabric blend is engineered to prevent odor buildup and maintain shape after washing, giving you a premium quality shirt that performs better than basic long-sleeves.

Can Under Armour long-sleeve shirts be worn in multiple seasons?

Yes, these shirts serve as great transition pieces between seasons. The moisture-wicking properties work in both warm and cool conditions - keeping you dry in the heat and providing additional warmth when it's cooler.

While they're designed for layering in colder weather, the quick-drying and breathable properties make them suitable for spring and fall when you need a little extra coverage.

What are the key features of Under Armour's long-sleeve technology?

Each style incorporates UA's signature moisture-managing technology, with fabrics that move sweat away from your body to help you stay dry. The shirts often feature athletic cuts with elastic cuffs and a relaxed fit, providing a comfortable range of motion.

Many versions include reflective detailing for enhanced visibility during early morning or evening runs, and some models incorporate ventilation panels for improved airflow.

Who should choose an Under Armour long-sleeve?

This style is particularly beneficial for runners, cyclists, and anyone who works out regularly, as the moisture-wicking properties prevent discomfort from sweat accumulation. The shirts also perform well for active commuting and outdoor enthusiasts who need both protection and performance.

Those with sensitive skin might appreciate the soft-touch fabrics and odor-resistant properties, while casual wearers enjoy the blend of performance features with a stylish look.

How do I care for an Under Armour long-sleeve?

These shirts perform best when cared for properly. We recommend machine washing in cold water with a gentle detergent to maintain the fabric's shape and quality. Avoid using bleach or fabric softeners, as they can damage the moisture-wicking properties.

Machine dry or tumble dry on low heat, and avoid dry cleaning unless explicitly stated on the care label. Hanging to dry also helps maintain the shirt's shape and prevents wrinkling.

What's the lifespan of an Under Armour long-sleeve?

With proper care, an Under Armour long-sleeve can last two to three years with regular use. The moisture-wicking and temperature-regulating properties typically maintain their effectiveness for at least one year, after which you might notice reduced performance and increased odor retention.

Signs it's time to replace your shirt include fading, thinning fabric, or noticeable odor despite proper care. The elastic cuffs and moisture-wicking properties tend to degrade first, so monitor these areas closely.
