You are Looking at a 1/2 or 1/3 zip Cycling Jersey(By Voler). I Give it a grading of 7,minimal wear for age, good shape. Made in USA. Tag says size Large, listed as a Large.. may fit smaller(Depending on how tight/loose you wear your clothes)....Read Measurements(compare them to a piece you own and you will get an idea of how it might fit)....My actual measurements are as follows. Top to bottom,27". Across the chest, from pit to pit,21.5".
