PumpEase are the world"s ONLY fashionable hands-free pumping bras. Does it matter if it"s pretty if you will rarely, if ever be seen in it? Considering the 9.6 billion dollar lingerie industry in which over 80% of purchases are made by women, we would say it does!Made from an 88% polyester/12% spandex high-performance technical fabric, PumpEase will hold your pump in place as securely for your 1000th pumping session as it did for your 1st. Our wonderful fabric is super soft and comfortable, easy to care for, breathable, durable, has exceptional stretch and memory (i.e. won"t bag out) and has quick-dry and wicking qualities.PumpEase feature patented, "no-stitch" horn openings, guaranteed to accommodate any breast pump on the market. Read, write, text, talk on the phone, use your computer or tend to your baby, ALL while pumping!Keep in mind that we don"t recommend being fit for a PumpEase until you are at least 36 weeks pregnant or a minimum of 2 weeks postpartum.
