    • The perfect t-shirt for summer!
Size: X-Large Color: Black (001)/White
Review Image by Nikki Nikki
Absolutely loved this shirt for my son, and he did too! The fabric is soft, breathable, lightweight, and the perfect dark gray. Heavy enough to not be see through, yet light enough to wear in extreme heat. Washes easily, and wrinkles are easily removed with a warm tumble dry. Love the length of the shirt, and would definitely recommend this quality shirt to others. ... show more

    • Perfect shirt
Size: Large Color: (323) Serpentine / / White
Perfect fit—lightweight, comfortable, and a great value for the price. Fits exactly as expected, and I’ll continue buying Under Armour.

    • Perfect casual shirt
Size: Large Color: Mod Gray (011)/Black
My 12-year-old son absolutely loves the Under Armour Boys' Tech 2.0 Short-Sleeve T-Shirt! It’s his go-to shirt for both sports and casual wear. The fabric is lightweight, breathable, and moisture-wicking, which keeps him cool and dry, even during intense activities. He especially likes how comfortable it feels, and the fit is perfect—not too tight or too loose. The design is simple yet sporty, and the shirt holds up well after multiple washes, without losing shape or color. It’s become a staple in his wardrobe, and I’d highly recommend it for any active boy who needs a versatile, durable, and comfortable shirt! ... show more

    • Another win for UA- and me!!!!
Size: Large Color: Black (001)/White
I absolutely love Under Armour, and this shirt is no exception. My 12 year old recently told me he doesn’t want to wear the shirts with the big logo in the center. He’s a devotee of UA, so I looked to see if they could accommodate his request. To be honest I think these are a step up from the quality of the more popular dry fit with the larger logo. They have almost a ribbed texture, yet they’re still dry fit. I ordered every color for him bc they were on sale and they are very flattering and fit as expected. I ordered youth large and he is about 5’4” and 120 pounds. He’s set for the school year and I know I won’t have to replace these until he outgrows them, bc UA holds up! I believe every time I purchase something from UA I am getting my money’s worth and then some. ... show more
