Review on Enhance Performance and Comfort with PowerLayer Men's and Boys' Long Sleeve Compression Baselayer Top - Crew Neck/Mock Neck by Will Bremer

I bought this product when baseball started but it was cold at night. My son is 7 years old, he plays in the playground for 7-8 years. He is about 4 feet tall and weighs 65 to 70 pounds. He wears a size 7 shirt. The boys came out small. Just to give you an idea of what size you should get. Fits perfectly, just like a compression shirt should. My child was warm under the jersey without having to wear a sweater. He's used it about 3 times so far. Holds up well and doesn't roll. Great product for winter sports.
