These are maternity support pants with pelvic support function. They are fleece-lined. I purchased them because I was due to give birth in the winter, but I didn't have a chance to use them, so I'm selling them. They have been opened and the box has been thrown away, so I will pack them and ship them. You can care for your pelvis just by wearing them. The soft, warm fleece material wraps around your belly to keep it warm. The wide waistband does not use elastic, so it is designed not to dig into your belly before and after childbirth. The stretchy material is comfortable for the final month of pregnancy and after childbirth. The double-cross pelvic belt, integrated with the pants, supports the pelvis just by wearing them. - Color: Black - Brand: Pigeon - Type: Maternity support pants - Features: Pelvic support, warmth
