This is a summer weight ponte knit with a gsm of 230.
Ponte de Roma is a double-knit interlock fabric that has stability and firmness in addition to flexibility and softness. Ponte fabric has a subtle matte sheen and incredible soft drape. Solid colours are the same on both sides. It is one of the easiest knits to sew and you don't have to finish the seams. The upshot is that it is very flattering on most figures. Prewash before cutting.
