Binding kit. comes with XL black half tank racerback binder by GC2B, a Large light skin tone binder by Underworks, and some 7 inch binding tape by transtape with some big and small nipple pasties of various colors. Both binders fit me well despite the difference in advertised size. There may be some discoloration in the tan binder from sweating in it but I washed it well before packing it up. #GC2B #Underworks #Binder
