The Under Armour Women's Performance Cotton Long-Sleeve T-Shirt in White is a clean, classic option that serves as one of the most versatile pieces in any women's wardrobe or team apparel collection. White offers a crisp, fresh look that works well in warm weather as a standalone layer and adapts easily to layering over sports bras or under jackets during cooler months.
Built from a 60% Cotton / 40% Polyester blend, this long-sleeve shirt brings together the qualities of both fabrics. The cotton component keeps the hand feel soft and breathable, which is especially important in a White shirt worn during activity, when comfort against the skin matters most.
The polyester component reinforces the construction and helps the fabric maintain its shape and brightness through regular washing, which is important for a white garment that needs to stay looking fresh. Set-in sleeve construction gives the shirt a neat, structured silhouette that keeps it looking intentional rather than oversized.
The open rib knit collar lies flat and against the neck, and the UA logo at the left side seam hem provides quiet brand recognition without drawing attention away from the shirt's clean aesthetic. White is a natural choice for organizations seeking a decoration-friendly base that accepts vibrant, full-color artwork with clarity.
