Great top for layering, super soft and warm
This Under Armour long-sleeve shirt was the perfect base layer under a sports jersey in cold weather. My son loved how it felt on his skin—it’s breathable, lightweight, and still kept him warm and comfortable. The size was perfect for my 6-year-old. It is a bit pricey, but I’m hoping it holds up well after many washes.

Great Buy!
I purchased the Under Armour Boys' HeatGear Long-Sleeve T-Shirt for my son to wear during his summer sports, and he absolutely loves it! The material is lightweight and breathable, keeping him comfortable even during intense activity. The fit is great, and it moves well with him while he’s playing. Definitely a quality piece that performs as promised. We’ll be buying more for sure!

Just as described
Sizing was right on. Fits perfectly just as described. Meant to be tight. Washes very well and is very boy durable! Thin and lightweight, but warm and a nice texture.

Nice for baseball
The shirt was the perfect weight and quality for a cold baseball night… My son loved this because the arms were extra long.

UA base layer.
Perfect base layer under my son's jersey. Light weight but provides enough warmth on the field while keeping his arms mobile enough to throw, pitch, catch, etc. Runs true to size.

El titulo de la camiseta dice 'Under Armour HeatGear camiseta de manga larga para mujer - 1253816, Medium, White/Steel', pero al desembalar muy claramente es talla para niños y así lo pone en la etiqueta de la camiseta. ¡Estoy indignada y no recomiendo este vendedor a nadie!
