Essential for windy days!
I'm 5'7 145lbs and size 37" chest. I wear s in capo Verona an Modena jerseys. I bought this vest in a small and it fits perfect. No slack , great fit and importantly looks very "pro" :) the front wind material is great while the mesh on the back keeps body temps regulated. No issues at all the the vest ! I wear the vest usually from temps low 50s to 60. Either over l/s jersey or s/s with arm warmers
