The Under Armour Men's Long-Sleeve Tech T-Shirt in Flawless offers a lighter, bright colorway that stands out during training and active use. Built on the proven UA Tech platform, this long-sleeve shirt is made from 100% polyester that delivers quick-dry performance, an ultra-soft touch, and a natural feel that avoids the rigid or plasticky quality of lower-grade synthetics.
Whether you train in the morning or spend your day moving between tasks, this shirt keeps you without drawing attention to itself. Under Armour's Moisture Transport System is integrated into the fabric construction, actively moving sweat from the skin's surface to the outer layer of the shirt, where it dissipates quickly.
This process runs continuously as you work out or stay active throughout your day, preventing the buildup of moisture that makes other shirts feel heavy and uncomfortable under pressure. Anti-odor technology works alongside the moisture management system, targeting and inhibiting the microbes that create workout odors before they can develop.
The raglan sleeve construction keeps the shirt's silhouette clean and athletic while freeing up the shoulder area for unobstructed movement in every direction. Throwing, pressing, rowing, or any overhead movement benefits from the increased range that raglan sleeves allow.
The curved hem with a slight drop tail offers reliable back coverage and a clean visual finish from any angle. A locker tag below the center back neck eliminates label irritation for a distraction-free wearing experience. The Flawless colorway adds a fresh, light tone that works well for spring, summer, and warm-weather programs.
