The Rossignol W Infini Compression Race Top is a women's race suit top that benefits from meticulous manufacturing and high-performance technologies. As with the tights, compression inserts help promote better blood return during exercise. It also features rib support strips to improve posture. Depending on the intensity of the exercise, you can adjust the level of ventilation with the zip at the collar, while the brushed inner lining provides additional insulation and is soft to the touch. Being very tight-fitting, it is recommended to refer to the size chart below to choose the right size.  Size selection guide:  Please note, these items run small, if you are unsure or between two sizes always choose the larger size for more comfort and mobility.  Rossignol Women’s ApparelSizeBustWaistHipsXS81 - 84 cm67 - 70 cm89 - 92 cmS85 - 88 cm71 - 74 cm93 - 96 cmM89 - 92 cm75 - 78 cm97 - 100 cmL93 - 97 cm79 - 83 cm101 - 105 cmXL98 - 102 cm84 - 88 cm106 - 110 cm Nordic Top Suit Rossignol ---W Infini Compression Race Top Dark Emerald
