This thin and very light top has a half-zip, making it easy to put on. The black sections on both sides are stretchy, allowing for ease of movement. The hem has elastic. Junior size 140. The tag has been removed because my child outgrew it before wearing it, but it is unused. *Please note that there may be creases from folding during shipping. #Windbreaker #Baseball #YouthBaseball #Junior Type...Top of uniform Sleeve...Short sleeve
