The material of the shirt does not have the stretch of leading athletic apparel brands such as UnderArmor's Coldgear but feels much warmer. After reading the reviews I ordered a size up and it was the right decision: Youth Large fit my 10 year old son very well with some room for growth. I liked the color (bright red), he should wear it to match his club kit. I will update the review after washing and use.

We live in Colorado and baseball season starts in the spring when it's very cold. This tank top was the perfect base layer for my son's yellow sweater and fit him perfectly. While his teammates had to add extra layers over them, my son was warm and comfortable and didn't need to wear a hoodie or sweater while playing! Great product and I love that it comes in multiple colors. This will be my base coat for all of our future uniform needs!
