- Reviewed in the United States on March 8, 2025Size: MediumColor: (840) Earthen Orange / / BlackVerified PurchaseGrandsons love the, fit, feel and style. I love being the awesome Grandma! No shrinkage that we have noticed so far, and true sizing. Never have to worry about the torso length either. My grandchildren (my children were the same way) are tall and thin, so torso length and shrinkage is always a concern. And the brand is a matter of pride with children after a certain age. I don't mind if the product lasts, resists fading, resists stains, doesn't shrink up with each wash, and can be washed simply without special treatment. I have 3 grandchildren and the boys are barely a year apart. My daughter has enough on her plate with extracurricular activities, sports, children who enjoy camping and an active lifestyle without clothing that requires special steps and delicate treatment. Underarmor is not an inexpensive brand, but what you get when it's new is what you have months later after active use and normal washing. That makes it less expensive in some ways than the cheaper brands. We are very happy and the boys feel good wearing it and it feels good to wear. Happy Grandma.
