My teenager grew so much in the last year and so I had to buy him a whole new wardrobe. He mostly wears Under Armour shirts, so I thought I’d try this dry fit shirt out.How this fits:My son is typically a men’s size small, but figuring he would grow out of it soon, I ordered him a medium. I’d say that this definitely fits true to size; it is a little baggy on him in the arms and stomach and goes down past the top of his pants, but it is fine in the chest. it doesn’t look so baggy to be out of place or weird looking. If you’re on the fence between sizes, you probably can’t go wrong either way but I’d recommend sizing up if you want a shirt that is larger in the chest.About the fabric:- This shirt is made of 92% polyester and 8 percent spandex. It’s extremely lightweight, flexible, and soft / supple / silky feeling. There is no pattern to the shirt - it’s just a plain dark black. It’s moisture-wicking and my son doesn’t get sweaty in it. It can be machine washed at 30 degrees with like colors and really should be air dried. Don’t use fabric softener with this shirt. The shirt can be ironed.About the shirt design:This shirt has a high rounded neckline and a typical men’s cut to the rest of the shirt (typical sleeve length and typical boxy men’s shape). There isn’t a logo on the outside of the shirt. There are no pockets. The shirt is completely tangles, with the size, company info, and care info all behind the neck. I really get annoyed when the size is printed on the neck but there is a paper care tag sewn in somewhere, glad this shirt doesn’t do that. This shirt is not see-through.Overall, my son likes this. He will wear it around the house or to school / working out in / whatever. It’s a very versatile shirt and it’s comfortable too. There were no missed stitches or problems with the fabric and feels about the same quality as his other dry fit shirts.
