棒球外套 スタジアムジャンパー
A sports [[jacket]] commonly worn by American high school/college students and athletes. Traditionally, the wearing of such a jacket indicates that the student has met a specified level of participation or performance on a varsity team.

Letterman jackets commonly have a large letter (hence "letter"man) on one side on the jackets chest, indicating typically the name of a school or team. The sleeves are often a different color from the jackets body. The jackets collar is often also horizontally striped.
