Kids authentic collection majestic fleece lined Red Sox jackets coat, kids youth size medium. Please check measurements, I estimate this would fit around a size 10/12. Front pockets, fleece lined torso with quilted arms, front zipper. Armpit across measures about 20.5 inches, total jacket length measures about 23 inches, sleeve measures 21 inches. I’m a New England mom and this is an excellent jacket for early spring season and September through November.
