Under Armour Youth Large Fleece-lined Sweat Pants.

These sweat pants were a gift for my son, and they were big on him at the time. They ended up buried in his drawer, and I don’t think he ever wore them. The waist is 15 inches lay flat, and from the crotch to the bottom the inseam is approximately 32 inches. Given the need for flex in the crotch, they probably fit more like a 30 or 31 inseam. My son thought they ran big.
