  • Playful pattern, great summer color. SUPER SOFT 50/50 Cotton/Polyester Blend.
Size: Large Color: Fire Rock Scramble
We love Under Armour (UA) brand in my family, so I was excited to spot this shirt - it's one of my kid's favorite colors. The color really great for summer - a slightly orange-y red shade. As a parent, I'll also note it's nice and bright and a less common shirt color so that can be strategically helpful if you're going somewhere crowded. The UA logo is playful, made out of rock creations. It's a super soft shirt, made of 50% cotton + 50% polyester blend. The size youth large (YL) fits my kiddo well, who usually wears around a size 10-12 (and occasional 14) in many retail brands - and it's long enough which is great since he's a taller guy. We have washed as we always do our dri-tech/workout gear - cold water (no fabric softener), line dry. It's been washed about 4-5x so far and is wearing beautifully. My kids are outdoor explorers, so they aren't too gentle on clothes, but I am feeling great about the durability of this item so far. Overall, this has been a huge hit and I plan to show my kids the listing page so they can pick other colors/patterns (they're fairly getting to ages where they want say in their wardrobes).. It feels like a good value for a comfy shirt from a strong brand. It came inside a clear retail poly sleeve, with tags on it noting MSRP of $22.00. ... show more

  • Awesome Shirt - Perfect for Active Kids!
Size: Large Color: Fire Rock Scramble
My son absolutely loves this Under Armour shirt, and so do I! The color is vibrant and looks even better in person, and the graphic is really cool – a nice change from typical athletic wear. As expected from Under Armour, the quality is top notch. The fabric is lightweight and breathable, which is essential for my active kid, whether he's playing outside, at sports practice, or just lounging around. It washes well and holds its shape and color, even after multiple washes. Plus, it's super comfortable for him to wear all day long. The fit is great and size is true. If you're looking for a durable, comfortable, and stylish shirt for your boy, this is definitely it. Highly recommend! ... show more

  • Comfy Boys T-shirt
Size: Medium Color: Downpour Gray Ua Summit
Why did you pick this product vs others?: This Under Armour shirt looks so nice on my son! I love the color and design. It fits him perfectly. The material is soft and lightweight. Will definitely buy him a couple different ones for his back to school shopping.

  • Grandson liked it!
Size: Medium Color: Downpour Gray Ua Summit
Our grandson turned 14 and I had no clue what to get him. We always give cash, who doesn't like that. But I always send a gift up to them also. Last time they came down to visit most of his shirts were this brand. So when I saw this shirt, I was very happy and pleased with the price too! The material is well made, looks good and comfortable. And it is true to size. He liked it and is already wearing it. That's all I wanted! ... show more

  • Soft and true to the ad
Size: Medium Color: Downpour Gray Ua Summit
This Under Armor brand kid's T is made of a soft material, and the T's color and design are true to the ad. This is a comfy Tshirt, but to be clear, is not quick-dry fabric. It is more for casual everyday wear. I was a little disappointed that the design is an iron-on, not a silkscreen. We will see how the design fares after several washings. You are paying a premium here for the brand name and logo. The T itself is a nice quality, so it still rates four stars in my book. ... show more

  • Good quality!
Size: Large Color: Harbor Blue Bass
Everyone knows the name and how they stand behind their product. This shirt is very soft and well made. The design on the front is perfect for fishing. It's true to size. Wash and wear, no ironing needed. Good value for the money!
