Frequently Asked Questions

• How do HeatGear, ColdGear, and UA Tech fabrics differ, and which should I wear for running or the gym?

  HeatGear is a lightweight, cool-to-touch polyester blend that wicks sweat and encourages rapid evaporation for hot-weather runs and golf; ColdGear traps warmth with a brushed interior and stretchy construction for cold conditions or layering. UA Tech is a loose, everyday polyester knit designed for fast wicking and casual training sessions when you want breathability with a relaxed fit. Pick HeatGear for high-heat workouts, ColdGear for chilly outdoor training, and UA Tech for gym days or low-intensity activities.
• How do I choose between compression, loose, and in-between fits in Under Armour tops?

  Compression fits sit snug against the body for muscle support and are best as baselayers or for high-intensity training, while loose UA Tech styles prioritize airflow and comfort for recovery or casual wear. In-between or “athletic” fits combine structure with 4-way stretch (elastane/Elasterell) to allow full range of motion without feeling restrictive. If a garment lists high elastane or 4-way stretch, you can size according to your usual chest measurement because the fabric will accommodate movement.
• How do the HexDelta Short Sleeve Tee, Streaker Run V-Neck, and Swyft V-Neck compare for running?

  The HexDelta Short Sleeve Tee (95% polyester/5% elastane) uses a hex-pattern knit for ultralight breathability and 4-way stretch, making it ideal for hot, fast-paced efforts. The Streaker Run V-Neck with UA Threadborne Microthread (100% polyester) is engineered for fast drying and reduced chafing on long runs. The Swyft V-Neck (50/50 polyester/Elasterell) balances microfiber quick-dry performance with extra stretch for a more forgiving, everyday run tee.
• How do materials like Charged Cotton and mesh panels impact comfort and drying time?

  Charged Cotton blends (like in the Warped Route tee) combine cotton’s soft hand with polyester’s faster drying and 4-way stretch, so you get comfort without the long-dry time of pure cotton. Mesh panels add targeted ventilation in high-sweat zones to increase airflow and speed evaporation, which helps regulate temperature during intense workouts. Together these choices offer a mix of softness, ventilation, and quicker drying than traditional cotton.
• What sizing tips should I follow when a top lists 4-way stretch, elastane, or a compression fit?

  For compression tops, choose the size intended for performance fit—if you prefer less compression, size up one to move toward a tight athletic fit rather than true compression. For garments with 4-way stretch or elastane/Elasterell, stick with your normal size because the fabric is designed to move with you and reduce chafing. Also check product-specific fit notes (e.g., “loose” UA Tech or “athletic” cut) and consider whether you’ll layer underneath when selecting a size.
